Theodorian Borca-Tasciuc
— Assistant Professor of Mechanical, Aerospace, and Nuclear Engineering,
Rensselaer Polytechnic Institute

— Ph.D.; Mechanical Engineering; University of California, Los Angeles (UCLA); 2000
— B.S., Physics, Bucharest University, Romania, 1995

Career Highlights:
Upon graduating from Bucharest University, Borca-Tasciuc spent several months as a research assistant for The Institute of the Physics and Technology of Radiation Devices, also located in Bucharest. He then joined Duke University's Department of Mechanical Engineering and Materials Science for over a year as a graduate student research assistant before beginning work on his doctorate at UCLA. He joined the Rensselaer faculty in spring 2001.

In 2004, Borca-Tasciuc received a Faculty Early Career Development Award(CAREER) from the National Science Foundation for research “Towards Engineering Thermal Transport and Energy Conversion in Nanomaterials Based Devices.” He also received a 2004 Young Faculty Researcher Award from RPI.

Borca-Tasciuc has served as a referee for the Journal of Heat Transfer, Journal of Microelectromechanical Systems, Journal of Micromechanics and Microengineering, Transactions on Electron Devices, Nanotechnology, IEEE Transactions on Nanotechnology, Applied Physics Letters, International Journal of Thermophysics, Journal of Physics: Condensed Matter, Petroleum Research Fund, the National Science Foundation (NSF) Review Panel for the Nanoscale Interdisciplinary Research Team (NIRT) Program, and for NSF proposals and American Society of Mechanical Engineers (ASME) conferences. He is a member of ASME, the Materials Research Society, and Sigma Xi.

Research Areas:
Borca-Tasciuc is the director of the Nanoscale Thermophysics and Energy Conversion Laboratory (NanoTEC) on the Rensselaer campus. His research concentrations include nanoscale/microscale heat transfer and energy conversion, microelectromechanical systems (MEMS), and nanotechnology. His studies in nanostructured thermoelectronics involve characterizing thermoelectric properties of thin-film nanostructured materials and individual nanowires, identifying high figure of merit nanostructures, and developing fabrication and testing strategies for low-dimensional thermoelectric energy conversion devices.

Borca-Tasciuc's research into thermal transport in nanostructures includes performing experimental measurements of thermophysical properties on both thin-film nanostructured materials and individual nanostructures, improving the understanding of the relation between structural and growth parameters and effective thermal properties of nanostructures, and optimizing the heat transfer in nanostructures by controlling the mechanisms responsible for heat transport at the nanoscale level.

In his research into micro- and nanoelectromechanical systems, Borca-Tasciuc is working on energy conversion, chemical and biological detection, fast optical switching, flow control, and inertial sensors, as well as test-structures for thermo-fluid and thermoelectric characterization.

His current research is sponsored by the National Science Foundation and Sandia National Laboratories.
