Preeti Yadav

 
2021 Ph.D. CSIR-National Physical Laboratory, India
2015 M.Sc. University of Delhi, India
2013 B.Sc. University of Delhi, India
 
The field of organic electronics has come a long way in the past two decades with development of OLED, smartphone displays, colored light sources and portable solar cells which have become an integral part of our daily lives. These technological advancements are enabled by innovation in materials design along with device engineering. Since the future of organic electronics relies heavily on novel materials, there is urgent need to develop high performing organic materials by low-cost synthetic approaches. My research work focuses on molecular design and synthesis of conjugated polymers, and study of their structure-property relationships for organic electronic applications.

Baitan Chakraborty

 
2021 Ph.D. Department of Chemistry, Jadavpur University, India
2014 M.Sc. Department of Chemistry, Jadavpur University, India
2012 B.Sc. Department of Chemistry, Jadavpur University, India
 
During his Ph.D., Baitan worked on the development of new cyclization strategies to access fused heterocyclic compounds containing nitrogen and oxygen. Most of his works focused on the exploitation of eco-friendly and cheap iron-catalysis. Earlier he had worked briefly on glycosylation reactions as part of his M.Sc. dissertation. He has joined OIST as a postdoctoral researcher in August 2022. His current research interest revolves around cross-dehydrogenative coupling (CDC) reactions for the syntheses of semiconducting pi-conjugated polymers. He is also motivated in achieving the target with successful application of iron-catalysis, avoiding the use of expensive and toxic transition metals. Music, literature and travelling are as integral parts of his life as is his research.

PhD Students

Nivedha Velmurugan

 
2019 M.Sc. Stella Maris College, Chennai, India
2017 B.Sc. Women's Christian College, Chennai, India
 

I received my MSc degree in 2019 from Stella Maris College, Chennai, India. My dissertation work was centred on the preparation of a Ru-based catalyst for the dehydrogenation of formic acid and bimetallic nanocatalysts in different compositions for the biomass conversion of furfural.

I joined OIST in Jan 2022, and my first lab rotation was with Prof. Christine Luscombe. Later, in Jan 2023, I joined the lab as a PhD student, and my thesis work will focus on the synthesis of a voltage-sensitive dye, ANNINE-6. A multi-step synthetic process that it is, C-H Arylation is my initial and immediate challenge, and I am tackling it One Step At A Time!

I read for academia, a little less than I read for pleasure. I am a natural at singing off-key and dancing off-beat. Please talk to me in Bollywood/Kollywood movie references.
