Recent News

[July 2015] Stony Brook’s Got the Power: How One University Earned Four Major Energy Research Awards in Less Than a Year.

[MAY 2014] Another academic year is in the books. Some notable happenings:

 • I was invited to join the advisory board of the Clean Energy Business Incubator Program (CEBIP, http://cebip.org ). This group fosters renewable and clean energy technologies within New York State, and provides resources for budding companies to grow and develop.

• Five students graduated from my group with their Master Degrees, They are:

        2. Mr. Hanfei Chen (staying on for a Ph.D. in my group)

        3. Mr. Chih-Chieh (Dennis) Lin (entering industry)

        4. Mr. Siddhartha Gadiraju(pursuing a Ph.D. at Virginia Tech)

        5. Mr. Yogesh Bedeker (joined Cummins in Indiana).    Congratulations to all!

 • One of the senior design groups that I advised won First Place among their class in their class. Seniors Connor Beierle, Brian Streckenbach, and Ankit Tyagi designed an automated battery changer for a quadcoper. Their project was entitled “Robotic Batter Exchange Station for a UAV”. Two other teams working with me did similarly impressive projects. Congratulations!

[April 2014] My students took first place in the Department’s annual poster session for the Industrial Advisory Board for their poster entitled “Thermoelectrically-driven sustainable sensing and automation systems for fault tolerant nuclear incidents”. Other faculty on the work include Prof. Lei Zuo and Prof. David Hwang. The graduate students who worked on this project include Mahder Tewolde, Hanfei Chen, Chih-Chieh Lin, He Tao, Gaosheng Fu (Prof. Zuo’ student), Tao Zhang (Prof. Hwang’s student).

[September 2013] I finally got around to putting my promotion file together, and was promoted to Full Professor.

[August 2013] ThermoLift, Inc., an incubator comany in the Advanced Energy Center here on campus, just won a large DOE grant that includes a subcontract for our group. The topic is to develop an advanced natural-gas-driven heat pump. We also have a separate SPIR project with ThermoLift for additional development work for this device.

[April 2013] We took first place in the Poster Session at the Advanced Energy Conference in New York City on April 30-May 1! The poster was entitled Thermoelectric-driven Sustainable Sensing and Actuation Systems for Fault-tolerant Nuclear Incidents, based on recent work from our NEUP program (see below). The lead author was Ph.D. Student Mahder Tewolde, along with additional students Gaosheng Fu, Di Liu, Tao Zhang, He Tao, Chih Chieh Lin, Hanfei Chen, Chao Nie, Weixiao Zheng, and Fan Liu. Faculty members on the program include Profs. Lei Zuo, David Hwang, John Metzger (deceased) and myself.Congratulations to all of the students on this achievement!

[October 2012] We won a spot in the 2012-2013 MaxTech and Beyond ultra-low energy use applicance design competition (http://maxtechandbeyond.lbl.gov/). The concept is to use cooler outside temperatures during fall/winter/spring to reduce refrigeration electricity costs. Eight teams were awarded $20k each to worko on the project for the 2012-13 acadamic year, and will compete for the best design on a webinar on May 23, 2013.

[January 2013] In collaboration with Brookhaven National Laboratories and Michigan Technical University, we recieved an ESTCP award from the Department of Defense to install a modern evaporative cooler on a DoD data center and assess energy savings. Details can be found here: http://www.serdp.org/Program-Areas/Energy-and-Water/Energy/Conservation-and-Efficiency/EW-201348

[Jun 2012]: I just returned from a month-long visit to Japan. I traveled on a Japan Society for the Promotion of Science (JSPS) Visting Fellowship and visited Tokyo, Matsushita, Tsukuba, Izuku, Hiroshima, and Toyama. My host researcher was Prof. Fushinobu in the Department of Mechanical and Control Engineering at the Tokyo Institute of Technology. I presented at the 2012 Nano-Radiation Conference on May 23-25 in Matsushita and attended the 2012 Japanese Heat Transfer Conference in Toyama on May 29-31. It was a very productive visit, and good to see many old friends as well as meet new ones.

[May 2012]: We just learned that we have been awarded a DOE NEUP award. The project is entitled "Thermoelectric-Driven Sustainable Sensing and Actuation Systems for Fault-Tolerant Nuclear Incidents." The 3-year, $600k grant will focus on developing thermoelectric-based sensing systems for nuclear power facilities in the event of plant blackouts. Co-PIs are Profs. Lei Zuo, whom with I have several other thermoelectric projects, and David Hwang at Stony Brook, and Prof. John Metzger, the Director of Nuclear Engineering from the Department of Mechanical Engineering and Materials Science at the University of Pittsburg.
