Prof. Berry’s research covers resource allocation problems that arise in networked systems ranging from communication networks to social networks. This work uses mathematical models to gain insights into such systems and draws on tools from stochastic modeling, optimization, economics and algorithms. Specific topics of current interest include developing distributed resource allocation techniques for wireless networks, dynamic spectrum sharing and wireless spectrum policy, understanding the role of incentives in network security and modeling learning and adoption in social networks.

Dr. Barton’s RF Power and Analog Laboratory investigates engineering challenges related to RF and microwave active circuit design, specifically in RF front-ends for communications, imaging, and telemetry applications in both commercial and defense spaces. The growing importance of these areas is tied to rising costs of energy and an interest in global energy consumption reduction, underscoring the need for development of energy-efficient systems. A major driving application is next-generation 5G radio, which has motivated increased interest in MIMO systems that also translates to defense applications such as phased array systems. Dr. Barton’s research has concentrated on three primary areas: (1) energy-efficient power amplifier (PA) design, (2) analog techniques for signal generation and linearization, and (3) integrated PA sensing and adaptation techniques. The combination of these technologies can result in efficient ‘smart’ transmitters able to adapt to environmental changes.

I am an astrophysicist working on the Event Horizon Telescope (EHT) project. I primarily study black holes with and develop imaging algorithms for the EHT.
I was born and educated in Japan. I received my undergraduate degree in Physics from Hokkaido University in 2010. Then, I completed my M.Sc. and Ph.D. programs in Astronomy at the University of Tokyo in 2012 and 2015, respectively, under the supervision of Prof. Mareki Honma at the National Astronomical Observatory of Japan (NAOJ) Mizusawa VLBI Observatory. I started to work at Haystack Observatory as a postdoctoral fellow in 2015.
