The focus of Professor Talke’s research is in the areas of medical device technology and information storage. 

In the area of information storage, Prof. Talke and his students have been involved for more than 50 years in studying tribology and mechanics of disk and tape drives, and more recently, the optimization of thermal flying height control sliders and heat assisted magnetic recording.

In the area of medical device technology, Prof. Talke and his students are involved in developing an intraocular pressure sensor for implantation in the human eye and the design of novel internet-enabled ophthalmic instrumentation.  In addition, research efforts on 3-d printed endoscopes, esophagus deflection devices, detachable bronchoscopes, and biofilm retardant catheters are under way.


The research in Professor Talke’s group is very interdisciplinary, combining aspects of mechanical engineering, physics, materials science and high precision instrumentation to advance information storage and biomedical device technology.
