Melih Onuş. Melih Onuş (8 February 1981 – 10 September 2020) was a Turkish mathematician, computer engineer and scientist. He represented Turkey in 1998 and 1999, at the International Mathematical Olympiad and was awarded a bronze and a silver medal, respectively. He died in the COVID-19 pandemic.

Early life and education
Melih Onuş, who spent his early years in Ankara, completed his primary education in Iltekin Primary School and his secondary education in Atatürk Anatolian High School. During his secondary education he represented Turkey at the 39th and 40th International Mathematical Olympiad and was awarded a bronze and a silver medal, respectively.

In 2003, he graduated from Bilkent University Computer Engineering Department by completing his B.Sc. Between 2003 and 2005, he worked as a research assistant in the Department of Computer Science and Engineering at Arizona State University in the United States. In the same period, in 2004, he attended a summer school in the Computer Science department at the ETH Zurich. In 2006, at Los Alamos National Laboratory in New Mexico, he conducted his work with Hristo N. Djidjev entitled "A Scalable and Accurate Graph Clustering and Community Structure Detection".  After completing his doctorate study entitled "Overlay Network Construction in Decentralized Networks" at Arizona State University under the supervision of Dr. Andr´ea W. Richa he returned to Turkey.

Academic career 
After returning to Turkey, he worked at TOBB University, Bilkent University and Çankaya University Computer Engineering Departments. He continued his academic life at Bartın University from 2016 until his death.

Death 
Melih Onuş was infected with COVID-19, while visiting his family in Ankara amid COVID-19 pandemic in 2020. He died at a hospital in Ankara on 10 September 2020. His father died 3 days later also from the virus. Both were buried in  Ankara Ortaköy Cemetery.
