The Complex Biological systems and Bioinformatics (CBB) lab, lead by Kaveh Kavousi, is part of the department of bioinformatics of IBB (Institute of Biochemistry and Biophysics), University of Tehran.

An interdisciplinary group of Ph.D. candidates in Bioinformatics, Biotechnology, Biochemistry, Biophysics, biology, medical sciences, and computer science and engineering, along with master and undergraduate students from various disciplines, through a systematic approach, try to better understand the nature of complex biological systems, ranging from interaction between intra-cellular components to inter-cellular relations in different resolutions and from interactions between organisms to interaction networks within organisms. Inferring and analyzing context-specific metabolic networks, co-expression and co-abundance networks, host-microbiome interactions, and heterogeneous networks are some examples.
