PhD Comprehensive Examination
As part of the requirements for the PhD program, I need to take pass a comprehensive exam . This exam involves an in-depth survey of the current state of research in my field (Transaction Processing in Blockchain and Blockchain Sharding), followed by a critical analysis of key papers and open problems.
Date and Time: September 16, 2024 14:00-16:00
Location: RV 2809 – SCCS conference room on the Riverfront Campus, Augusta University.
Advisory Committee Members
My PhD advisory committee includes the following members:
- Dr. Costas Busch (Major Advisor)
- Dr. Abdullah Al-Mamun
- Dr. Dariusz Kowalski
- Dr. Hoda Maleki
- Dr. Peter Robinson
- Dr. Gursimran Walia (External: Graduate Program Director)
Oral Exam Title:Transaction Processing in Blockchain Sharding: A Survey
