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.

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.

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 rman@itbm.nagoya-u.ac.jp!

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 tl71@queensu.ca.

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 ym25@queensu.ca

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 jfd6@queensu.ca !

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 alex.veinot@queensu.ca if you have any questions about the group or the city.

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 15zta@queensu.ca!

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!
