Jason Chruma   was born and raised in the Phoenix Metropolitan Area of Arizona (USA) and   earned his BS in Chemistry with Honors from the University of Arizona in 1997   working under the mentorship of Prof. Robin Polt. In 2002, he earned his PhD   from the University of Pennsylvania studying under Prof. Amos B. Smith, III,   and this was followed by an NIH post-doctoral fellowship at Columbia   University from 2003-2005 with Prof. Ronald C. Breslow. He began his   independent career as an Assistant Professor in the Department of Chemistry   at the University of Virginia in 2005 before moving in August of 2012 to   Sichuan University where he is now a Professor and Director of Doctoral   Studies.

Sichuan   University Top-Notch Undergraduate Teacher Award (2013)

National   Institutes of Health (USA) Postdoctoral Fellowship (2003-2005)

Admission   Direction to Ph.D. Program and Postdoctoral Associates

1.Organic Chemistry: Organic Synthesis;   Transition-Metal Catalysis; Natural Product Total Synthesis

2.Bioorganic Chemistry: Small-Molecule   Peptidomimemics, g-Amino Acid-based Foldamers; Modulation of Cellular   Differentiation

3.Green Chemistry: Green Organic Synthesis

4.Physical Organic Chemistry: Synthesis and   Evaluation of Single-Crystal Organic Spintronic Devices (in collaboration   with the College of Physical Sciences and Technology)


Research   Interests

Prof.   Chruma’s research interest focus on developing new methods for the synthesis   of nitrogen-containing organic compounds and other biologically-active   natural products involving such “green” methods as transition-metal catalyzed   decarboxylative alkylations and intramolecular pericyclic reactions. The   intent is to discover new molecular probes and tools to elucidate the   biomolecular mechanisms involved in cellular differentiation and aniokis. Additional   interests involve the design and synthesis of novel foldamer scaffolds and   fluorescent linchpin reagents for bioconjugate synthesis.
