Bio

Professor Skowronski obtained his Ph.D. degree in Solid State Physics from Warsaw University (Warsaw, Poland). His post-doctoral appointment was at Massachusetts Institute of Technology where he used junction spectroscopy to study compound semiconductors. This was followed by work at Cabot Corp. on growth of compound semiconductors. In 1988, he moved to Carnegie Mellon University where he focused on deposition of thin films for electronic applications, fabrication of devices for energy efficient electronics and neuromorphic computing, and electron microscopy.

Research

We aim to discover, understand, and fabricate novel materials, phenomena, and device structures for information technology. The overarching driving force for the group's research is increasing energy efficiency especially for applications in Artificial Intelligence. Specific research directions include artificial synapses for neuromorphic (brain-like) computing, non-volatile memory and logic devices, devices scalable beyond the current technology limits, and, in general, world of "more-than-Moore" electronics.

All projects are highly collaborative requiring interactions with and visits to other institutions. Ongoing collaborations include CMU’s Department of Electrical Engineering, Intel, IBM, IMEC, Oak Ridge National Laboratory, and National Institute of Standards and Technology.
