Sos agaian, ph.d.


Dr. Sos Agaian is the UTSA Peter T. Flawn Distinguished Professor of Electrical and Computer Engineering. He was recently named UTSA's Innovator of the Year. Notably, Agaian is researching image enhancement for use in computer-aided cancer detection. To date, Agaian and his colleagues have developed an algorithm that:

- assists pathologists in locating and scoring cancerous tissue regions

- provides more consistent and accurate cancer grading and scoring

- reduces the time and cost to process biopsies, and

- removes the need to have slides reviewed and graded by multiple pathologists.

While at UTSA, Agaian's research has led overall to 26 invention disclosures, 17 patent applications filed, two patents issued and three technologies licensed. Over the last year alone, his research led to six invention disclosures, three provisional patent applications filed, two full patent applications filed and three technology licenses. Additionally, the licensee of his technology provided more than $100,000 in sponsored research funding to his laboratory, and it hired one of Agaian's doctoral students following graduation.
