  • Dec 10: Vishnu Paidimarri, our group's longtime site and lab admin and SSDL's only civil engineering student has graduated with a BS degree. Congrats to Vishnu! We wish him all success in the future too.
  • Dec 9: SSDL meets for Fall group dinner at Boba Fusion.
  • Nov 18: Prateek Kulkarni successfully defends his MS thesis titled "Nonlinear and Inertant Acoustic Metamaterials and their Device Implications." Congratulations Prateek!
  • Nov 11: Anuj Rekhy successfully defends his MS thesis on "Low-Frequency Acoustic Noise Mitigation Characteristics of Metamaterials-Inspired Vibro-Impact Structures." Anuj has the distinction of being SSDL's first Master's graduate. Congratulations Anuj!
  • Oct 18: Dr. Manimala wins a 2016 DARPA Young Faculty Award to investigate metamaterials-inspired MEMS devices. This award provides $498,000 of research funding for 2 years with the possibility of a follow-on $500,000, 1 year Director's fellowship. The DARPA YFA aims to "identify and engage rising research stars in junior faculty positions at U.S. academic institutions and introduce them to Department of Defense needs as well as DARPA’s program development process." The YFA award bestows national recognition to the research underway at SSDL. More updates to follow soon.
  • Oct 6: Aditya Agrawal, graduate student in IEM joins SSDL as lab assistant. Aditya will provide support to research activities underway at SSDL. Welcome Aditya!

Summer 2016

  • Jul 31: SSDL summer group meets up at Dr. Manimala's place for a barbeque and try out the new garden railway!

      

  • Jul 27: OSU collaborates with Textron Aviation - Engineers from Textron's acoustics group partnered with SSDL to conduct acoustic transmission loss testing of aircraft structural panels with various treatments. The testing was conducted in OSU's acoustics lab using the reverb-anechoic chamber facility according to ASTM and SAE standards. Textron team comprised of Gonzalo Mendoza, Dr. Wenlung Liu, Greg Hayward and Lloyd Kronk. OSU team comprised of Dr. James Manimala, Anuj Rekhy, Andrew Chambers, Mykale Holland and Alexader Svetgoff.
