N. Asokan will be joining the David R. Cheriton School of Computer Science in September 2019 as a Professor and David R. Cheriton Chair in Software Systems.

He is currently a Professor of Computer Science at Aalto University (since 2013). He was a Professor of Computer Science at the University of Helsinki from 2012 to 2017. Between 1995 and 2012, he worked in industrial research laboratories designing and building secure systems, first at the IBM Zurich Research Laboratory as a Research Staff Member and then at Nokia Research Center, most recently as Distinguished Researcher.

Asokan's primary research theme is systems security broadly, including topics like the development and use of novel platform security features, applying cryptographic techniques to design secure protocols for distributed systems, applying machine learning techniques to security/privacy problems, and understanding/addressing the security and privacy of machine learning applications themselves.

Asokan received his doctorate in Computer Science from the University of Waterloo, MS in Computer and Information Science from Syracuse University, and BTech (Hons.) in Computer Science and Engineering from the Indian Institute of Technology at Kharagpur. He is an ACM Fellow and an IEEE Fellow. He directs the Helsinki-Aalto Center for Information Security.

Shalev Ben-David joined the David R. Cheriton School of Computer Science as an Assistant Professor on July 1, 2018 after a postdoctoral fellowship at the University of Maryland.

His research interests are in classical and quantum complexity theory. 

Trevor Brown joined the David R. Cheriton School of Computer Science in the fall of 2018.

Before joining the Cheriton School of Computer Science, Trevor was a postdoctoral researcher at the Institute of Science and Technology in Austria. Before that, he was a postdoctoral researcher at the Technion, Israel Institute of Technology. He completed his PhD at the University of Toronto.

Although he was in the theory group at the University of Toronto, his research is closer to systems work than theory. He cares greatly about rigour, whether in theoretical or experimental work. His research currently revolves around concurrent data structures, especially lock-free ones. He is also interested in transactional memory, non-volatile memory, and techniques for coping with non-uniform memory architectures.

Responsibilities:

• Oversee administration of PhD program
• Event planning including graduate orientation
• Manage TA assignments and TA & RA payroll
• Assist with NSERC/OGS/QE2 competitions
• Assist with CS graduate web pages

Kimon Fountoulakis is an Assistant Professor in the David R. Cheriton School of Computer Science and a member of its Scientific Computation Group.

Previously, Kimon was a postdoctoral fellow and Principal Investigator at University of California Berkeley in the Department of Statistics and ICSI. He worked with Michael Mahoney. Before that he completed a PhD in optimization at University of Edinburgh under the supervision of Professor Jacek Gondzio. 

Kimon's most recent work focuses on large-scale optimization and its application to local graph clustering. He has also worked on parallelizing optimization and local graph analytics algorithms.

Kimon's past work includes higher-order optimization methods for machine learning and signal processing problems.

Toshiya Hachisuka will be joining the David R. Cheriton School of Computer Science as an Associate Professor in September 2020.
