HBM4: turning a bandwidth headline into useful computation
A wider memory interface changes the performance ceiling, but locality, arithmetic intensity, capacity and thermal limits determine what an application actually gains.
Advanced computing.
A long-term research interest in the interaction between compute, memory, data movement and energy use.
Think beyond the processor.
As applications become more data-intensive, system design needs to consider how information moves as well as how it is processed. Our research perspective connects hardware architecture, memory and software behaviour. Explore our technical reviews for sourced developments and the system-level questions they raise.
Research interests
System architecture
The balance between processing, memory, networking and storage.
Data movement
The cost and performance implications of moving information through a system.
Efficient operation
Understanding workload behaviour, resource use and practical operating constraints.
Open to a focused
research conversation.
We are interested in collaboration around a clear technical question, complementary expertise and a defined contribution.

CXL 4.0: a faster link does not make all memory local
CXL extends the memory-system design space. Link speed, topology, locality and tail latency must be considered together before treating expanded memory as a substitute for local DRAM.

Advanced packaging: measurement is part of the architecture
As more functions move into a package, material interfaces and measurement access become system-level decisions. Reliability must be designed in rather than inferred from a working demonstration.
