Hey there! My name is Hriday, with a lot of conflicts on how to pronounce it properly, which I better not discuss here. I was born and brought up in a small town named Durgapur (200 Km from Kolkata) in India. Then moved to Kolkata for my B.Sc. (Chemistry Hons.) at St. Xavier’s College. Stayed in the same city and completed my M.Sc. at Jadavpur University. After which, I moved to Canada and joined Prof. Jens Müller’s Lab to pursue my Ph.D. where I worked on making boron-bridged strained ferrocenophanes and used them as monomers for boron-containing metallopolymers. After spending an amazing time there in Saskatoon, I moved to Kingston in February 2019 and joined Crudden’s Lab as a Postdoctoral Research Fellow. Here I am working on an exciting project of making biosensors where NHC molecules will be used as a “glue” between electrode surfaces (e.g., gold) and biological pathogens.

Other than Chemistry, I am passionate about Photography. I also enjoy cooking delicious Indian dishes and listening to (mainly) Bollywood music in my spare time.

Hey, my name is Jacky Yim. I joined the Crudden Group @ ITbM in Nagoya, Japan in April 2015. Although I was born in Hong Kong, I grew up mostly in Greater Toronto Area (Markham, Ontario). I went to the University of Western Ontario (now known as Western University) for my undergraduate studies, where I got my B.Sc. in chemistry. During that time, I worked in the laboratory of Prof. J. P. Guthrie (computational organic chemistry) as part of NSERC-USRA and of Prof. F. Lagugné-Labarthet and Prof. K. Griffiths (experimental materials chemistry) for my bachelor’s thesis project. After undergrad, I moved across the country to rainy (and sometimes sunny) Vancouver for my graduate studies at the University of British Columbia. Here, I joined Prof. Laurel Schafer’s group (organometallic chemistry) and worked with various titanium and zirconium amidate complexes, which were used to catalyze hydroamination and hydrozirconation reactions. After which I thought I should move further away from Toronto, so I joined the satellite Crudden group at Nagoya, Japan. Since then, I have worked on the development of new synthetic methods to assemble multiply-arylated methanes, as well as the synthesis of targeted multiply-arylated methanes for medicinal purposes. Outside of chemistry, my main hobby is food! Any cuisine and any style, both making it and consuming it!

I grew up in the Comox Valley on Vancouver Island on the west coast of British Columbia, Canada. After completing my Bachelor of Science at the University of Victoria in 2009, I moved to Vancouver to complete my PhD under the supervision of Professor Parisa Mehrkhodavandi at the University of British Columbia. My dissertation focused on the design and synthesis of a large family of dinuclear indium catalysts for the controlled polymerization of lactide. Following the completion of my PhD in 2014, I moved to the University of Toronto to undertake a postdoctoral fellowship under the supervision of Professor Datong Song, where I worked towards the activation of small molecules through homogenous transition metal catalysis as well as the design and synthesis of new metal precursors for applications in atomic layer deposition. I recently moved to Nagoya, Japan in November of 2017 to join the Crudden group working on the synthesis and catalytic applications of NHC functionalized gold clusters. In my spare time I enjoy baking, reading, crafting and binge watching movies and tv shows.

Hi folks! I was born in England and grew up mainly in the entirely not made up town of Swadlincote in the lovely county of Derbyshire. I obtained my undergraduate degree at the University of Leeds, and during this time I spent an exchange year in Canada at McMaster University. The discovery of poutine and hockey was enough to make me want to move back to Canada, and after some time in industry in both England and Canada, I enrolled at the University of Alberta for my PhD with Prof. Eric Rivard. Since then I have travelled around the western half the North America a lot, including a year working with Prof. Phil Power at UC Davis and some time in western Washington state near Seattle (which I highly recommend!). I joined the Crudden group in Jan 2018 with the goal of putting a variety of NHCs on every gold surface or particle in sight.

When not in the lab I enjoy spending time in the kitchen, playing soccer or squash, and dreaming up new molecules that I have no hopes of ever being able to synthesize. If you ever need me, drop me a line at!

Hey everyone! My name is Renee, and I joined the Crudden Group @ ITbM in Nagoya in April 2015. I was born in Hong Kong, studied there for a few years before making a move to Vancouver, Canada. I liked Vancouver so much that I did both my undergraduate and graduate studies at University of British Columbia. In 2009, I obtained my Honours Bachelor of Science degree in Chemistry, during which I worked in Prof. Peter Legzdins’ lab in activation of inert C-H bond using tungsten nitrosyl complexes. Since then, I began my adventure in materials chemistry and obtained my Ph.D under the supervision of Prof. Michael Wolf. During this time, I developed novel metal-containing (mostly Pd and Au) nanomaterials towards methane oxidation reaction. I was then given a golden opportunity to continue my love for anything nano, to work with NHC-containing gold nanomaterials at the satellite Crudden Group at Nagoya, Japan!

Outside of lab, I love eating (especially Japanese food), drawing digital artwork, gaming, and traveling all over Japan. Need me? Contact me at!

Srijit was born and raised in Yavatmal, India and received his B.Tech/M.Tech degrees from the Department of Biotechnology, Indian Institute of Technology (IIT) Kharagpur, India. During his bachelor’s, he worked on studying cellular effects of anticancer drugs on different cancerous cell lines and developing microfluidics-based rapid DNA hybridization system for disease detection. During his master’s, he worked on developing and studying chitosan nanoparticles-based drug delivery system in Entamoeba histolytica. In 2015, he moved to Kingston to start his PhD in interrogation of metallic nanostructures for sensing and biosensing applications. He developed new surface plasmon resonance biosensor based on plasmonic crossed surface relief gratings and developed miniaturized biosensing platforms to detect pathogenic E. coli in clinically relevant concentrations. In addition, he also investigated chemical sensing of contaminant via surface enhanced Raman spectroscopy and developed low-cost sensing substrates using MiiCraftTM 3D printer and EnvisionTECTM 3D bioplotter.

I was born and raised in Eastern Europe, in the beautiful city of Kyiv, the capital of Ukraine. My B.Sc. and M.Sc. studies in Analytical Chemistry were carried out at the Kyiv Taras Shevchenko University. My work under supervision of Olga A. Zaporozhets was focused on developing solid-state analytical reagents for sorption-spectroscopic and visual test determination of heavy metal ions. From those times comes a habit of meticulous cleaning of all lab glassware as well as my fascination with hiking, biking, and speleology. I gained broad experience and got a real passion in Materials Chemistry (for instance, mesostructured mesoporous silica or metal nanoparticles) while working as a Junior Research Associate at the Institute of Surface Chemistry (Kyiv, Ukraine). Big changes came to my life upon moving to Canada to continue my study at Western University (London, Ontario) under the guidance of John F. Corrigan and Yining Huang. My Ph.D. research was focused on semiconductor structured materials, in particular, 3D arrangements of CdS and CdSe nanoclusters. I moved to Kingston and joined the Crudden group at Queen’s University as a Postdoctoral Research Fellow in July 2018 to work towards the preparation of novel NHC-stabilized metal nanoclusters and making use of such their properties as remarkable photophysics and catalytic activity.

When I am not doing chemistry, I am still experimenting in my kitchen with cooking new dishes. My spare time is mainly devoted to the most demanding long-term project of my life – raising my daughter. Together, we enjoy reading, swimming, and solving various puzzles. Please, feel free to contact me at

Konnichiwa, my name is Yuki and I am from Gifu, Japan. I completed my PhD in 2017 under the supervision of Dr. Toshiaki Murai at Gifu University, where I worked on the synthesis of chiral organophosphorus compounds. During this time, I got a chance to work with Dr. Cathleen Crudden for three months. After I finished my PhD, she gave me the great opportunity to come back to Canada. Here I am investigating new ways to transform the carbon-sulfur bond.

In my spare time, I enjoy working out to be the next Captain America, going on adventures outside, cooking and eating food. If you have any questions, feel free to email me at

My name is Karthik Devaraj, and I am originally from India. I completed my International Master in Catalysis, Molecules, and Green Chemistry in 2012 at the University of Rennes 1, France under the supervision of Prof. Pierre H. Dixneuf and Prof. Christophe Darcel. In my masters, I worked on C-H functionalization reactions in environmentally friendly solvents. Next, I started my PhD in 2012 at the University of Uppsala, Sweden under the supervision of Dr. Lukasz T. Pilarski. My PhD work focused on C-H functionalization and aryne-based methodology. After completing my PhD in 2017, I worked as a postdoctoral researcher for one year under the supervision of Dr. Xavier Bugaut, and Prof. Jean Rodriguez, iSm2, Aix-Marseille University, France. My postdoctoral research is centered on the enantioselective dearomatization reactions and pyrylium atropisomers. I have been working as a postdoctoral researcher under the supervision of Prof. Cathleen Crudden since November, 2019. My research work here focuses on stereospecific iterative cross-coupling reactions. Apart from work, I read books about spirituality and philosophy.    

My name is Joey DeJesus and I was born and raised in the greater metropolitan area of Orlando, Florida.  I did my bachelor’s degree at the University of Central Florida and had the opportunity to work with both Prof. Yi Liao’s and Prof. Karin Chumbimuni-Torres’ groups and worked on synthesizing visible light photoacids and alkali metal ionophores, respectively.  Deciding Florida was too dang hot, I moved further north and did my Ph.D. at the University of Tennessee in Knoxville.  I worked with Prof. David Jenkins’ group and worked on multiple projects that applied NHC chemistry to SERS sensing (collaboration with Prof. Jon Camden’s group), chiral ligand design and chemistry of macrocyclic tetra NHC complexes with primarily iron, uranium and thorium.  Since Tennessee wasn’t cold enough, I moved to Canada and joined the Crudden group in January 2020 to work on projects applying new NHCs towards design of metal nanoclusters and functionalizing metal surfaces.

In my spare time, I enjoy fulfilling activities such as low speed running and cycling, as well as being awful at video games.  I am also very passionate about eating good food and drinking more coffee than is probably healthy for me.  If you have any questions about the group, feel free to reach out by emailing me at !

My name is Alex Veinot, and I joined the Crudden group in September 2017 as a PhD student. I’m originally from the very small town of Middleton, Nova Scotia (population of 1800), and enjoyed my first visit to Kingston because of its small town feel. I completed my Bachelor’s (Honours) degree at Acadia University (Wolfville, NS, 2015) under the supervision of Dr. Bobby Ellis, and during this time I became interested in synthetic inorganic chemistry. Next, I completed my Master’s at Saint Mary’s University (Halifax, NS, 2017) under the supervision of Dr. Jason Masuda, where I continued to pursue inorganic chemistry and found a new interest and appreciation for X-ray crystallography. During my time in the Crudden group I will continue to study organometallic chemistry, while complimenting my synthetic background with some techniques specific to materials chemistry. During my free time I enjoy being outdoors exploring Kingston’s many walking trails, fishing, and playing golf. I highly recommend Queen’s for anyone who is hesitant about moving to a big city like Toronto or for anyone who enjoys being outdoors, feel free to contact me at if you have any questions about the group or the city.

My name is Ishwar, I moved from New Delhi, India to Toronto to pursue my undergraduate studies at UofT. After a long 4 year journey through the world of chemistry, I’m here in Kingston working under Dr Crudden as a graduate student.

Outside of lab I do powerlifting, some amateur photography and listen to east-coast hip hop music.


Hello! My name is Zach Ariki and I am originally from Denver, Colorado. I completed a B. A. in Chemistry at Boston University in 2014 where I got my feet wet in laboratory chemistry under the supervision of Dr. John Porco Jr. As chance would have it, in 2012 I bumped into Cathy at the Beckman Scholars Conference in Irvine California and I learned a lot of interesting things about her and her chemistry. I was intrigued to hear she ran a lab at the Intstitute of Transformative Bio-Molecules (ITbM) at Nagoya University in Japan. Flash forward 2 years and I am living in Japan conducting research towards the preparation of bio-active thyroid hormone receptor analogues. This year was truly a great experience for me. In 2015, I was recruited by Cathy to her lab at Queen’s University and I have been conducting research towards the development of new C-S bond transformations ever since!

In my spare time you can find me in the squash courts or at a computer working on my graphic design projects. Some day I hope to own a small army of pugs and open my own sake distillery! Feel free to contact me at!

I did an undergraduate thesis project at Trent University with Dr. Andrew Vreugdenhil and Dr. Steven Rafferty on biocatalyst immobilization in amorphous silica. I graduated with a BSc in chemistry in 2019 and joined the Crudden lab in September of 2019.

I am very happy to be back in Kingston. I spend most of my free time playing sports like soccer, running, playing chess, and watching anime. I’m very excited to begin my research in the Crudden group and learn a lot more about chemistry and working in a lab!

Hi Everyone, my name is Nicole Dozois. I joined the Crudden Group in Fall 2018 to complete my fourth-year thesis and B.Sc. Honours in Chemistry and pursue a M.Sc. through the Accelerated Master’s Degree Program in Chemistry. After my third year of my B.Sc., I spent 16 months on an internship at DuPont Canada. Here, I had the opportunity to participate in the optimization and scale up of chemical synthesis operations and analyze products produced by a variety of process development projects. I really enjoyed the organic work I did, and I hope to continue learning and growing in this field in the Crudden Group. Outside the lab, I enjoy travelling and adapting to new places as I was born in Germany and have lived all over North America including Alaska, Alabama, Quebec, Oklahoma and many more places. I also enjoy cozying up with tea and a book when I have spare time. Please feel free to reach out to me at if you have any questions or want to chat.

Undergraduate Students

Hello! My name is Julia Antoniw and I began my fourth year undergraduate research project in the Crudden group in September 2019. Originally from Toronto, I moved to Kingston in 2015 to complete a B.Sc. Honours in Chemistry. Over the past four years I have been dipping my toes into different areas of chemistry. In the summer of 2017, I did research in the Fekl group at UofT Mississauga on metal-catalyzed [18F] fluorination of diaryliodonium salts. In 2018, I completed a 12-month internship at the vaccine manufacturer Sanofi Pasteur. In the summer of 2019, I worked in the Cunningham group at Queen’s investigation block-random copolymers applied as stabilizers in emulsion polymerization. I am excited to be working on a project in organic chemistry and I look forward to gaining new knowledge and skills.

Outside the lab, I am an enthusiastic but mediocre runner and I enjoy running along the Kingston waterfront. I also enjoy yoga, reading, cooking, baking and spending time with friends and family. Please feel free to reach out to me at if you have any questions or want to chat. 

Visiting Researchers

Hallootjes! My name is Joyce Kromwijk and I have lived all my life in a small town called IJsselstein, which is located right in the middle of the Netherlands. In September 2018 I started with the master Nanomaterials Science at Utrecht University. For the past year I worked in the group of prof. Weckhuysen where I studied the cobalt-catalyzed CO2 hydrogenation reaction using various spectroscopic techniques. I am very excited to work in the Crudden group from March until August to complete my degree and learn about a totally different chemistry than what I am used to. In my free time I like to play guitar, visit concerts, read a good book and go out for a run.

Group Trips & Activities

The Crudden group works hard, but we have lots of fun outside the lab as well! It’s not unusual to find us at the Grad Club celebrating a publication, an award, or just some great results.

Kingston is great for winter activities. The public skating facilities at the market square are a short walk from campus, and there are lots of hills for a fun afternoon of sledding.

In the summer, we switch to warm weather fun, and we usually have at least one beach day, and take a long weekend to go camping.

There’s a lot fo fun to be had, both in the lab and out!
