Dr. Bijoy Dey

Biography

Dr. Dey grew up in India and his high school teacher wanted him to become a Mathematician for his repeated top rankings in mathematics. As he was pursuing his undergraduate degree he became interested in chemistry and obtained a B.Sc. (Honors) with physics, chemistry and math concentrations.

By the end of his college days Dr. Dey knew he would only want to be a physical chemist, so he finished his Master's in chemistry with specialization in physical chemistry. He chose to attend Panjab University’s Center of Advanced study in Chemistry for doing research. This was possible because of the fellowship he received from the Council of Scientific and Industrial Research, Government of India. His thesis dissertation was titled “Density functional and quantum fluid dynamical studies on many-electron systems” which was derived from six of his publications during that period.

During the next few years Dr. Dey conducted research at several Institutes on different topics in physical chemistry. It was at the University of Waterloo that he first started teaching graduate level courses.He then joined the faculty of chemistry in Augustana University in 2008, where he taught, researched and published with students until he finally joined the chemistry faculty at Claflin University in the fall of 2015.

Dr. Dey has published 27 papers in peer reviewed journals of moderate to high impact factors. He has two patents and one book published with Wiley publishers. Several of his publications have received numerous citations from people other than myself (scifinder.com) and one of his papers on “quantum dynamics with Bohmian mechanic“ appeared as one of the reference articles in the textbook “Introduction to quantum mechanics: A time-dependent perspective“ widely used for graduate course in quantum dynamics. He is in the habit of keeping himself abreast of recent developments in the field of chemistry, and this helps him write research proposals in his continual effort to seek funding and enables him to do research with students.

Dr. Dey loves spending time with his children. When his children are sleeping, he watches soccer and cricket, his all-time favorite sports.

Dr. Dey typically teaches courses in physical chemistry in the upper division and general chemistry in the lower division. He also teaches quantum mechanics, biophysical chemistry and chemistry seminar courses. He mentors 2-4 students each year in a variety of research projects.

If you are a Claflin student and interested in research you are encouraged to stop by Dr. Dey's office. He will be happy to discuss different research projects and opportunities to get you involved. Students can typically work during the academic year or apply for a research stipend during the summer.
