Nov 23: Our research group got together at the Texas Roadhouse for our Fall group lunch. Those present in the photo below are: Left row (front to back) - Will, Bablu, Zack, Timmy, Jenelie (Timmy's wife), Paul and Zander; Right row (front to back) - Jully, Alessio, Dr. Manimala and Samarjith.

Nov 13: Representatives from the US Army Corps of Engineers, Construction Research Laboratory accompanied by OSU's Vice President for Research, Dr. Kenneth Sewell and others visit the acoustics lab and SSDL. Dr. Manimala provided a tour of the facilities including the anechoic-reverb chamber to the visitors.

Nov 9: SSDL hosts lab tour for prospective graduate students from regional universities during their visit to OSU-CEAT. The tour was coordinated by graduate student Samarjith Biswas with graduate students Milkyas Afework, Muhammad Ali Bablu, Paul Akinmolayan and undergrad student Alessio Lozzi participating.

Oct 22: LeeAnn McElroy, OSU alumna and Technical Fellow, Spirit AeroSystems tours SSDL and interacts with Dr. Manimala and graduate students Timmy, Milkyas and Clement.

Oct 16: Dr. Manimala and grad student Milkyas Afework attend the 2019 International Digital Image Correlation Society (iDICs) conference in Portland, OR. They presented a paper titled, "Robust Heuristics-Enabled, Vision-Based Sensing for Road Traffic Artifacts," based on SSDL's foray into heuristics-based vision technologies. Photos below.

Sep 25: SSDL participates in the planning meeting for OSU's Center for Integrated Building Systems (CIBS), an NSF IUCRC Center. Dr. Manimala made an oral presentation on 'Meta-Acoustic Claddings for HVAC Applications' and graduate student Zander Svetgoff presented a poster on it.
