  • Join us in HerbertFest, a 2-day workshop to celebrate Herbert Edelsbrunner's 60th Birthday at Institute of Science and Technology (IST) Austra on June 20-21, 2018, which I am a co-organizer. Registration page is here with deadline April 15.
  • We received the new NSF TRIPOD award to develop foundations of data science from the perspective of "Discovering structure, shape and dynamics in data"! See the NSF announcement here.
  • Together with Chen Chao and Dimitris Metaxas, we received an NSF AitF grant to develop topological algorithms for 3D/4D cardiac images.
  • Congratulations to Justin Eldridge (co-advised by Misha Belkin and myself) who received OSU Presedential Fellowship 2017! Great job Justin!
  • Together with Partha Mitra from CSHL and Misha Belkin at OSU, we recently received a NIH RO1 grant on retrieving and analysing neuron structures.
  • We have an opening of a postdoc position to work with Tamal Dey and myself at OSU. We are looking for someone with strong background in different geoemtric / topological data analysis related areas and who is interested in computational topology and geometry. The position is supported under NSF RTG grant (see description here ). Applicants must be US citizens or permanent residents. Interested candidates should send your CV to Tamal and myself.
