Mariya Zheleva

Dr. Mariya Zheleva is an Assistant Professor in the Department of Computer Science and Director of the Ubiquitous Networking Laboratory (UbiNET Lab) at the University at Albany. In 2019, she became the recipient of the highly competitive National Science Foundation’s (NSF) Faculty Early Career Development (CAREER) Award. This award came with funding of $510,494 which is being used to develop a framework for spectrum measurement and a long-term, integrated program of research, education and outreach related to spectrum sharing. Dr. Zheleva’s CAREER Award came at the heels of another NSF grant of $1.5 million to support her research helping rural communities in Upstate New York to substantially improve emergency preparedness and response. She was also a recipient of a 2019 University at Albany President’s Award for Exemplary Public Engagement for her leadership in closing the connectivity gap in rural communities.


Dr. Zheleva’s research focus is on wireless networks for infrastructure-challenged regions, characterized with low-bandwidth Internet gateways, lack of reliable electricity and sparse populations. In order to connect such regions, she has designed distributed cellular network systems to provide voice, text messaging and data connectivity. She is also working on Dynamic Spectrum Access systems for long-distance high-bandwidth connectivity.

In the past, Dr. Zheleva has worked on other projects related to wireless networking including monitoring, medium access control for 60 GHz networks and smart phones.








Frank Lind

I was born near Portland, Oregon. After attending high school in Seattle, I studied at the University of Washington, where I received a Bachelor of Science degree in Physics and a Bachelor of Science degree in Computer Science in 1994. I then joined the UW Geophysics Program and pursued studies leading to the Doctor of Philosophy in Geophysics in 1999. My work there focused on passive radar observations of the aurora borealis. Currently, I am a Research Engineer at MIT Haystack Observatory, where I develop and operate ground- and space-based radio science instrumentation.

My research focuses on radio science, advanced radar and radio arrays, space plasma physics, software radar, novel sensors and signal processing, and satellite instrumentation.

Dale Hatfield


Dale N. Hatfield is currently an Executive Fellow at the Silicon Flatirons Center for Law, Technology, and Entrepreneurship and an Adjunct Professor in the Interdisciplinary Telecommunications Program – both at the University of Colorado at Boulder. Prior to joining the University of Colorado, Hatfield was the Chief of the Office of Engineering and Technology at the Federal Communications Commission (FCC) and, immediately before that, he was Chief Technologist at the Agency. He retired from the FCC and government service in December 2000.

Before joining the FCC in December 1997, he was Chief Executive Officer of Hatfield Associates, Inc., a Boulder, Colorado based multidisciplinary telecommunications consulting firm. Before founding the consulting firm in 1982, Hatfield was Acting Assistant Secretary of Commerce for Communications and Information and Acting Administrator of the National Telecommunications and Information Administration (NTIA). Before moving to NTIA, Hatfield was Chief of the Office of Plans and Policy at the FCC.

Hatfield has over fifty years of experience in telecommunications policy and regulation, spectrum management and related areas. He holds a BS in electrical engineering from Case Institute of Technology and an MS in Industrial Management from Purdue University. In May 2008, Hatfield was awarded an Honorary Doctor of Science degree by the University of Colorado for, inter alia, his commitment to the development of interdisciplinary telecommunications studies.

Hatfield was the founding Executive Director of the Broadband Internet Technical Advisory Group (BITAG). He is currently serving on the FCC’s Technology Advisory Council (TAC) and on the Commerce Department’s Spectrum Management Advisory Committee (CSMAC) and served as an independent Director of Crown Castle International Corp. from July 2001 until his retirement in May 2017.

Phil Erickson

I am an associate director at Haystack (2020; previously assistant director from 2015), Principal Research Scientist at MIT, and I also lead Haystack’s very productive Atmospheric and Geospace Sciences Group.  I conduct fundamental research on the near-Earth space environment, primarily through radio-based experiments and data analysis using a variety of remote sensing techniques involving ground- and space-based data.

I am the lead principal investigator for the community-oriented Millstone Hill Geospace Facility (MHGF), a prime North American space science observatory sponsored by the National Science Foundation for mid-latitude ionospheric remote sensing and scientific analysis.

Recently, the Group has initiated direct measurements from low Earth orbit for ionospheric physics.  I am the principal investigator for the forthcoming Auroral Emission Radio Observer (AERO), a NASA Heliophysics funded small satellite mission led by MIT Haystack.  I am also a co-investigator on the Haystack-led and simultaneously launched NASA Vector Interferometry Space Technology using AERO (VISTA) small satellite mission.

I am a co-director of the education and public outreach efforts at MIT Haystack, spanning undergraduate research programs, graduate student interactions including graduate student committee membership, K-12 classroom units and outreach, and public Observatory tours and lectures.

I am an active member of the HamSCI collective for amateur-professional activities and research, engaging the 750,000+ amateur radio operators in the United States for fundamental ionospheric citizen science. This includes active amateur radio participation (call sign W1PJE).

I serve as a journal reviewer, public lecturer, workshop session convener (CEDAR, GEM, AGU Space Physics and Aeronomy), and member of various space science committees. These include the Committee on Radio Frequencies (CORF), convened by the National Academies of Science, Engineering, and Medicine (NAS) Board on Physics and Astronomy. CORF considers the needs for radio frequency requirements and interference protection for scientific and engineering research, and coordinates the views of U.S. scientists. In general, CORF acts as an important channel for representing the interests of U.S. scientists in Earth science and radio astronomy passive and active remote sensing matters.

My training in ionospheric physics and Thomson/incoherent scatter radar theory and practice (B.S. 1987; Ph.D., 1998) came from the seminal Space Plasma Physics group within Electrical Engineering at Cornell University, where my principal advisors and mentors were Donald T. Farley, Michael C. Kelley, and Wesley E. Swartz. I have been a Haystack staff member since 1995.

I grew up in Schenectady, NY, home of General Electric’s seminal Research and Development Laboratory, where both my mother and father worked (microbiology and metallurgy, respectively) and where the great Irving Langmuir, coiner of the word “plasma” for 99% of the known universe, conducted research. I live in central Massachusetts with many hobbies including music, photography, history of technology, and keeping up with my son James and art historian wife Sarah.
