Derek C. Tretheway, Ph.D., Assistant Professor, Mechanical and Materials Engineering

Derek C. Tretheway, Ph.D. received his B.S. (1993) in chemical engineering from the University of California, Berkeley and his Ph.D. (2000) in chemical engineering from the University of California, Santa Barbara. His research interests include fluid mechanics, micro- and nano-scale science, and cell biomechanics. He seeks to understand transport phenomena at small length scales in a variety of microfluidic devices (MEMS-micro-electro-mechanical systems, and BioMEMS- biomedical applications of MEMS) and in biological flows. Practical applications of his research include DNA chip gene sequencing, sensors for chemical and biological detection, and pharmaceutical assays.

Since arriving at Portland State, Dr. Tretheway has taught classes in thermodynamics and microfluidics and has been a faculty advisor for MME senior capstone projects. He recently received a National Science Foundation (NSF) grant, along with MME adjunct associate professor Sean S. Kohles, for $214,226 to develop "An Integrated Optical Tweezers/Micro-PIV System to Investigate Cell Biomechanics." Currently, he has three proposals pending including a $1.2 million NSF Nanoscale Interdiscplinary Research Team proposal with PSU physics professor, Jun Jiao, MME professor Mark Weislogel, and MME adjunct professor Larry Melvin entitled "Nanotextured Surfaces for Passive Fluid Control and Enhanced Transport in Micro/Nanochannels."

Dr. Tretheway is a member of the American Physical Society and the American Society of Mechanical Engineers. He has served as a reviewer for several journals and NSF grant proposals and has presented at numerous conferences on such topics as "Single Pixel Evaluaton of Microchannel Flows" and "Effects of Soluble Gasses on Apparent Fluid Slip in Hydrophobic Microchannels."

Derek Tretheway was attracted to Portland State in part because of the urban location and easy access to recreational areas, but mostly because he felt that there is a positive energy in the Maseeh College of Engineering and Computer Science in terms of research and collaboration-"we're expanding rapidly, and it's exciting to be a part of that growth," he said.

In his free time, Dr. Tretheway enjoys fishing, hunting with his chocolate lab, Mia, and backpacking.
