Andrew B Greytak is an American Professor of Chemistry. Currently, he is working as an Associate Professor of Chemistry at the University of South Carolina[1]. Through his research, he tries to understand the underlying properties of semiconductor nanostructures and how these properties can be modified by controlling the chemistry at their surface.

Education and Career

Andrew Greytak completed his Bachelor of Science (S.B.) degree in Chemistry from the Massachusetts Institute of Technology in 2000. Later he earned his Ph.D. from Harvard University in 2006. Dr. Greytak then conducted his postdoctoral studies at MIT from 2006 to 2010.

In 2010, Dr. Greytak was appointed Assistant Professor of Chemistry at the University of South Carolina[2]. In 2018, he was promoted to Associate Professor[3].

Greytak Research Group

Dr. Greytak started his own research group at the Chemistry and Biochemistry department at the University of South Carolina in 2010[4]. Since the beginning, his research group, named Greytak Group[5], is trying to develop new synthetic strategies for fluorescent semiconductor nanocrystals, called quantum dots (QDs).

Photoluminescent Quantum dot often display very different optical and electronic properties than their native bulk crystals due to their characteristic smaller size. When the size of these semiconducting nanocrystals gets less than 10 nm in diameter[6], their optical properties start to change dramatically due to quantum confinement effect. As the size of the QDs work as a function of confinement energy, both the absorption and fluorescence emission of the QDs can be tuned by changing their size and shape during their synthesis[7].

Greytak group’s primary focus is to understand and control the underlying chemical and physical properties of these semiconducting nanocrystals at their surface by tuning their size and shape during synthesis. The group develops different types of synthetic methods and purification strategies for QDs that that allows progressively precise and sophisticated control over the physical and chemical properties of QDs. Such controlling power let the group to develop high performance QDs that can be used to make advance solar cells, wearable devices, in biomedical applications of nanocrystal-based imaging and therapeutic agents[8].
