Recent focus of Professor Ramanathan's research group is in the area of genomic networks. In a collaborative project with faculty in Biochemistry, Chemistry, and Chemical & Biological Engineering, his group is working on developing computational tools for genome foundries and genome-aided biodesign. Ongoing research projects focus on developing computational algorithms for elucidating DNA-protein binding, for optimizing metabolic pathways, and for identifying gene regulatory networks.
The longer term focus of his research is on developing the architectures, the protocols, and the mechanisms needed to meet the diverse quality of service requirements of applications in wireless and wireline networks. One of the research thrusts involves developing communication support for sustaining end-to-end gigabit throughputs to mobile hosts in future Internet. Another thrust involves developing sensing and communication algorithms in millimeter wave networks. In additional to developing the necessary theoretical algorithms, research also involves implementing and experimenting with these algorithms on network testbeds.
