PhD and Postdoc Position Openings
I am looking for Postdoc and PhDs in my team. Experience in processor design (on ASIC or FPGA), hardware/Software implementation etc. is desired. If you are interested in a Postdoc or PhD position, please contact me with a CV.
In addition to the aforementioned positions, there are scholarships for the Chinese students funded by the China Scholarship Council Scholarships scheme. The deadline for applications to be received is 17 January 2020.
Why PhD with us?
+ PhD students receive close supervision. Students meet their supervisors whenever they want.
+ Funding is available for 3.5 years (which is generally the span of a PhD).
+ We do *not* require a GRE score.
+ Bachelors degree (BS) students with excellent grades are eligible for direct PhD admission.
+ PhD curriculum does *not* involve any major coursework. It is research-focused and hence more fun!
+ Researchers collaborate. We have weekly group discussions and seminars.
+ We are social. Work is fun here!
TeamI work closely with my PhD and UG/MSc project students.

Master/Bachelor project topics:
1. Design and analysis of post-quantum public-key cryptographic schemes
2. their efficient implementations
3. their side-channel security
4. Privacy-preserving cloud computing
I am interested in developing efficient algorithms, design methodologies and hardware/software architectures for computation-intensive tasks targeting new-generation heterogeneous computing platforms. I have contributed to the progress of hardware security by designing and engineering cryptosystems, analyzing their physical security properties and implementing countermeasures against side-channel and fault attacks. I am one of the developers of SABER KEM which is a candidate in NIST's 2nd round Post-Quantum Cryptography Standardization project.
My research experience spans two broad areas: Public-key Cryptography and Privacy-preserving Cloud Computing using Homomorphic Encryption, with focus on implementation aspects.
Implementation of post-Quantum Crypto in HW/SW.
Hardware Acceleration of Homomorphic Encryption.
Elliptic Curve Cryptoprocessor.

I received the PhD degree with `Summa cum laude with congratulations from the examination committee' (~top 5%) from the Computer Security and Industrial Cryptography (COSIC) group, Department of Electrical Engineering (ESAT), KU Leuven, Belgium. My doctoral thesis received the 'IBM Innovation Award 2018' which recognizes of an outstanding doctoral thesis in informatics. I joined the School of Computer Science, University of Birmingham in September 2018.
