Welcome to SSS@Lehigh!

We are the Scalable Systems and Software Research Group at Lehigh University!
Designing and building parallel, concurrent, and distributed systems are our major focus. Our research topics include:

Programming Languages
Transactional Memory
Concurrent Data Structures
Speculative Parallelization
Memory Allocators
LLVM
Memory Persistence
Distributed Synchronization

Centralized and Distributed Transactional Systems
Blockchain
Consistency
Fault-Tolerance and Replication
Consensus
Computer Architecture
Energy Efficient Architectures

We are always looking for motivated students and productive collaborations. If you find these topics interesting and you are eager to contribute, contact us.
