The IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm) was held at the Sheraton Hotel & Marina in San Diego, CA, May 31 – June 3, 2022. This was the 21st ITherm, which was first held in 1988. The conference was historically held every other year until 2016 when it switched to an annual schedule. ITherm 2022 was sponsored by the IEEE Electronics Packaging Society (EPS). ITherm has partnered with IEEE EPS peer conferences, including the International Workshop on Thermal Investigations of ICs and Systems (THERMINIC) in Europe, and the Electronics Packaging Technology Conference (EPTC 2022) in Asia.
The ITherm 2022 program consisted of 16 professional development workshops and three full days of technical presentations in four tracks with 48 sessions in which 173 papers were presented. Additional technical events included three keynote addresses, five panels, five technology talks, a student poster competition, and a student heat sink design competition.
Keynotes
On the first day of the conference, Dr. Vijay Narayanan, IBM Fellow and Senior Manager at IBM, gave a keynote address entitled “Accelerating Deep Learning With Analog In-Memory Compute” discussing hardware innovations to address the computational demands of the AI boom.
On the second day of the conference, Dr. Mark Jennings, Senior Technical Leader for Vehicle Energy Management & Propulsion Systems Analysis for Ford Motor Company, gave a keynote address entitled “Thermal Management Challenges for Battery Electric Vehicles” describing the challenges in thermal management system integration and vehicle connectivity.
On the final day of the conference, Dr. Tajana Šimunić Rosing, Full Professor and holder of the Fratamico Endowed Chair at the University of California–San Diego, gave a keynote address entitled “Hyperdimensional Computing System Design & Thermal Management” discussing the opportunities and challenges presented by hyperdimensional computing.
Best and Outstanding Papers
Awards given for the best and outstanding papers in each track, based on judging from reviews and inputs from session and track chairs, were unveiled to the attendees.

Student Poster and Networking Session
The student poster and networking session provided an opportunity for students to interact with industry and academic leaders in their fields. This venue enabled students to connect with possible future employers and to receive feedback on their work. The student posters were subjected to two rounds of judging based on technical merit, clarity, self-sufficiency of the content, originality of the work, visual presentation, and oral presentation with the best and outstanding posters selected for each technical track, and one poster was selected as the best overall.

Student Heat Sink Design Challenge
The ASME K-16/IEEE EPS Student Design Challenge is a team competition in which students design, analyze, and optimize an additively manufactured, aluminum heat sink to cool a constant heat flux power electronics module subject to natural convection. Designs were submitted by teams from around the world and evaluated by a team of experts based on a series of design and manufacturing criteria. For the 2022 competition, the top 7 most effective and creative designs were printed using additive manufacturing facilities at GE and tested using state-of-the-art test equipment at the University of Utah. The 7 finalist heat sinks are shown in Figure 1.
