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

He was 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 was the founding director of the Helsinki-Aalto Center for Information Security.

Trevor Brown joined the David R. Cheriton School of Computer Science in the fall of 2018 as an Assistant Professor. He works in the area of multicore computing (both systems and theory). His current research focuses on non-uniform memory architectures, memory management, lock-free synchronization, distributed data structures, non-volatile memory and transactional memory.

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

Toshiya Hachisuka joined the David R. Cheriton School of Computer Science as an Associate Professor in September 2020. Previously, he was an Associate Professor at the University of Tokyo, where he led his research group on computer graphics. Before coming to the University of Tokyo, he was an Assistant Professor at Aarhus University from 2011 to 2014. 

Toshiya received a Ph.D. in Computer Science from the University of California at San Diego in 2011 and a B.Eng. from the University of Tokyo in 2006. His research interests include light transport simulation, computational statistics, numerical analysis, and physically based animation. He has a number of publications spanning these topics in the area of computer graphics.

Xi He joined the David R. Cheriton School of Computer Science as an Assistant Professor in spring 2019.

Xi graduated from National University of Singapore with double degree in Applied Mathematics and Computer Science. 

She completed her PhD at Duke University, working with Prof. Ashwin Machanavajjhala. Her research interests span the areas of privacy and security for big-data management and analysis.

Responsibilities:

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

Gautam Kamath joined the David R. Cheriton School of Computer Science in July 2019.  

Gautam was a PhD student at MIT, affiliated with the Theory of Computing group at CSAIL. He is interested in principled tools for statistical data science, with a focus on settings that are common in settings of modern data analysis (high-dimensions, robustness, and privacy). 

He was a Simons-Berkeley Research Fellow at the Simons Institute for the Theory of Computing for the fall 2018 semester program on Foundations of Data Science and the spring 2019 semester program on Data Privacy: Foundations and Applications. 

Srinivasan Keshav is the Robert Sansom Professor of Computer Science in the Department of Computer Science and Technology at the University of Cambridge and a Fellow of Fitzwilliam College. Previously, he was a Professor at the David R. Cheriton School of Computer Science.

Although he started out as a researcher in computer networking in 1988, since 2010 his focus has been on reducing the carbon footprint of energy generation, transportation, and buildings. For the past couple of years, he also worked on improving the performance of the Hyperledger Fabric blockchain so that it can be used as the foundation for highly-scalable energy systems, such as for transactive energy and renewable energy certificates. 

He has recently turned his attention to the carbon sequestration and biodiversity potential of forests, looking at both conservation and restoration.

Dr. Shane McIntosh joined the Cheriton School of Computer Science an Associate Professor in July 2020. 

His research area is in empirical software engineering. More specifically, he has focused his research on release engineering. He has made significant research contributions in intelligent release pipelines, code review analysis, and mining software repositories. As of October 2019, Dr. McIntosh has published 16 journal papers and 32 conference papers, all in the top research venues and leading journals of the field. His papers have been cited almost 2400 times with an h-index from Google Scholar of 28. He has been invited to many international workshops, such as Shonan and Dagstuhl.

Dr. McIntosh has also contributed to the software engineering community as a program committee member in several top conferences, such as ICSE, FSE, and OOPSLA. He has been the co-chair of multiple workshops on release engineering and the co-chair of several tracks in top tier conferences. He was just awarded a Canada Research Chair (Tier II) at McGill, and he was a Vanier Canada Graduate Scholarship holder. He was one of two Ph.D. graduates from the Queen’s University class of 2015 to be recognized with the Academic Gold Medal from Governor General of Canada for his Ph.D. work.
