The center mentors and assists students/researchers towards determining commercialization potential of technologies coming out of U labs. Students from all backgrounds are competitively selected and receive a partial stipend. They are trained in the various disciplines involved with early stage business development. Mr. Mondal is pursuing his Ph.D. under the direction of Dr. Alonso P. Moreno, developing new in vitro techniques using microelectrode array embedded in two and three dimensional cell cultures for studying the effects of controlled gap junction communication on electrical and metabolic propagation.
CVRTI's Katie J. Sciuto has received a 2012 NSF Graduate Research Fellowship. The NSF Graduate Research Fellowship provides a portable stipend for the fellow to use at the institution of his/her choice. The Fellowship is highly competitive and only 10% of applicants receive the award. Ms. Sciuto will pursue her Ph.D. at CVRTI studying the effects transgenic relative to pharmacological modulation plays on the relationship of gap junctions and cardiac electrophysiology in the laboratory of Dr. Steve Poelzing.
