We are very pleased to announce that Dr. David Bodine has been awarded the 2022 Outstanding Early Career Award by the AMS Scientific and Technological Activities Commission! Dr. Bodine has also recently been elected as Adjunct Assistant Professor in OU's School of Meteorology.
The ARRC is very excited to once again host an annual workshop. This event will take place March 3rd and 4th, and will be open to research sponsors, Strategic Partner Consortium (SPARC) members, and charitable donors to the ARRC.
If you have not received an invitation despite your organization falling into one of these categories, please contact Professor Nathan Goodman at goodman@ou.edu.
Plan for an all-day workshop on the 3rd, and half day on the 4th followed by the advisory board meeting. Events on the 4th should wrap up by early afternoon. Pictured is our group from 2020's Industry and Government Days.
We're excited to announce that the ARRC is expanding our professional engineering team. Multiple positions are available for each of the job postings in the links below. Please help in our expansion process.
Precious Jatau is a PhD student in the School of Electrical and Computer Engineering, advised by Drs. Tian Yu and Valery Melnikov.
Scholarships, Awards and Publications:
• Advanced Radar Research Center (ARRC) Student Journal Paper Award (2021)
• Farrar Endowment Scholarship for Electrical and Computer Engineering (2020)
• William H. Barkow Scholarship for Electrical and Computer Engineering (2019)

Current Research:
"My current research project focuses on the development of a machine learning algorithm to classify bird and inset echoes for S-band dual-polarization radars. This algorithm can be applied to NEXRAD radar network, enabling large-scale monitoring of biological migration activity. Potential benefits include better understanding of the spread of avian diseases, improved collision avoidance of migrating birds with aircraft, and improved velocity azimuthal display IVAD) wind retrieval using only passive wind tracers like insects."
Interests and Plans After Graduation:
"After completing my PhD, I plan to pursue a career in Machine Learning / Software Engineering."

Randall Summers is a masters student in the School of Electrical and Computer Engineering, advised by Dr. Mark Yeary. Randall's current research investigates the impact of various predistortion algorithms on the performance of radar systems. Randall said, "I'm also looking into beam-shaping algorithms for phased arrays and ways to quickly evaluate super-resolution algorithms.
