PhD Student Souley Cissokho joins the group!

Very pleased to announce that Souleymane Cissokho is joining our research group for the Spring semester 2025! Souley joins after completing his undergraduate degree at Rose Hulman and with experience in acoustic signal processing from Idaho National Labs. Very glad to have him on board! He will be working on acoustic sensing technologies.

Antarctica Balloon Launch Successful

Tufts University School of Engineering is headed to the stratosphere once again on a high altitude balloon! A successful launch of the 2024 Salter Test Flight – Universities from McMurdoStation, Antarctica, occurred on Dec 21 2024. Many thanks to NASA – National Aeronautics and Space Administration Balloon Programs Office and the Columbia Scientific Balloon Facility, particular Christopher D. Yoder and Don Banfield, for the opportunity. The balloon carries, among other payloads, the SPARROW-6 experiment part of which is the Tufts Sonic Anemometer from my research group at Tufts University (Tufts University Department of Mechanical Engineering). The flight is expected to float in the stratosphere near 125,000 feet for 5 to 10 days. After recovery we will have a wealth of data on stratospheric winds! Sure hope my code is running correctly!!! Safe travels!

Podcast in “Across Acoustics” Goes Live

A podcast describing some of our work on the Mars Sonic Anemometer (and Tufts High Altitude Sonic Anemometer) is now live! Thanks very much to AIP Publishing and the Acoustical Society of America for taking the time to produce this and helping spread the word on the Mars Sonic. Many thanks to co-authors Don Banfield and Ian Neeson particularly, and to NASA – National Aeronautics and Space Administration for funding and supporting this work.
