PhD student. Analyzing CcpA affinity to cre boxes (catabolite responsive elements) and response of B. subtilis to membrane protein overproduction stress.
The main area of my expertise concerns protein sorting and secretion in Gram-positive bacteria, such as Bacillus subtilis and Staphylococcus aureus.
The Gram-positive bacterium B. subtilis is well known for its high capacity to secrete proteins into the extracellular milieu, which has led to its exploitation as a "cell factory" for secreted proteins. Nevertheless, the secretion of heterologous proteins of pharmaceutical importance is frequently inefficient. This applied problem has been a major
