People in the CHSLT

Cosme Furlong received his BEng from the University of the Americas, Mexico, in 1989, and his MS and PhD in Mechanical Engineering from the Worcester Polytechnic Institute (WPI), Worcester, MA, in 1992 and 1999, respectively. He was visiting Post-doctoral investigator at BIAS, Bremen, Germany in 2002. He held the positions of Research Professor and Assistant Professor of Mechanical Engineering at WPI where he currently is a Professor working in the field of Nanoengineering, Science, and Technology (NEST).

Ryszard Pryputniewicz founded the Center for Holographic Studies and Laser micro-mechaTronics (CHSLT) shortly after joining the WPI faculty in 1978. He had previously spent six years at the University of Connecticut, where he had a joint faculty appointment in the School of Engineering and the Health Center. His research interests include theoretical and applied aspects of microelectromechanical systems (MEMS), smart sensors and structures, and holographic interferometry.

Peter Hefti is the lab manager at the Engineering Experimentation Laboratory for the Department of Mechanical Engineering at WPI. Before he joined WPI in 1982 he worked in the optic laboratory of the Research Center at Brown Boveri Company, now ABB, in Switzerland for 10 Years. He joined the Center of Holographic Studies and Laser micro-mechaTronics (CHSLT) laboratory to assist Professor Pryputniewicz in the field of nondestructive testing using optical metrology.

K. Pooladvand received both his B.Sc. and M.Sc. degrees in Mechanical Engineering from the University of Tehran, Iran. He is currently a Ph.D. student in mechanical department at Worcester Polytechnic Institute (WPI) and working as a researcher in the CHSLT. Koohyar's current research interests include additive manufacturing, high-speed optical metrology, residual stress estimation and evaluation, inverse problems, and thermo-mechanical modeling. His field of research also includes the computational fluid dynamic (CFD), radiation heat transfer modeling, optimization, inverse boundary design of furnace, and thermo-fluidic modeling and experimentation.

Payam is a Ph.D. candidate in Manufacturing Engineering at Worcester Polytechnic Institute (WPI). He received his B.Sc. in Mechanical Engineering from Azad University, Iran in 2007, his M.Sc. in Mechatronics Engineering from Sharif University of Technology, Iran in 2010, and he joined the CHSLT labs from 2014 as a research assistant. His research is mainly focused on developing non-destructive high-speed holographic methodologies to study the transient motions of the human tympanic membrane (eardrum) in live samples to provide the necessary tools for investigation of sound energy transformation by the middle ear. These tools may also be applied to the clinic for better diagnosis of the tympanic membrane and middle-ear pathologies. His research is part of a collaboration with Massachussetts Eye and Ear Hospital, in Harvard/MIT Division of Health Sciences and technology

Former members of the CHSLT

Morteza Khaleghi received his PhD in Mechanical Engineering from the Worcester Polytechnic Institute (WPI), in May 2015. Here at the CHSLT labs, he spearheaded developments of Holographic Interferometric systems for biomedical and industrial applications. Morteza is currently a Visiting Scholar at the Stanford Biomedical Optics Group and the Ginzton Laboratory of Stanford University. He also holds Senior R&D Scientist position at the Earlens Corporation, working on the world's first hearing aid that uses light to transmit sound.

Ivo Dobrev received his PhD in Mechanical Engineering from the Worcester Polytechnic Institute (WPI), in July 2014. During his research at the CHSLT labs, he was involved with the development of high-speed optical metrology systems, and experimental work on non-destructive testing for bio-medical, industrial and art conservation applications. Ivo is currently a Postdoctoral researcher at the Otolaryngology Department of the University Hospital of Zurich, where he is involved with experimental and analytic work related to bone conduction hearing and middle-ear mechanics.
