Laser flow cytometry is an important tool  for detection and analysis of tumor cells and other cellular markers of diagnostic and therapeutic value. Laser flow cytometry is extensively used for study of cellular proliferation, phenotype  marker expression and  in tumor diagnosis and for monitoring response of cancer patients to therapy. 

The Indo-US Cytometry workshops were initiated in 2001 by Dr. Awtar Krishan from the University of Miami  in collaboration with Dr. Ranbir Sobti of Panjab University, India and Dr. Arvinder Singh of BD Cytometry, India with the express purpose of interfacing Indian researchers with experts in cytometry from abroad. With the collaboration and active support of instrument manufacturers (who provide their latest instruments and staff for the workshops), the Live Education Task Force of the International Society for Advancement of Cytometry (ISAC) and an important group of core faculty members, a large number of  researchers from all over the world  have been trained in the latest applications of laser flow cytometry in bio-medical research. 

We have used the Indo-US workshop model to conduct workshops in ASEAN countries (Kuala Lumpur, Singapore, Bangkok, Jakarta), Turkey (Istanbul, Marmara, Ankara, Antalya) , Riyadh in Saudi Arabia and in China (Shanghai, Beijing, Chengdu and Hong Kong) and in Taipei, Taiwan. Similar workshops have also been held in San Diego, Miami, Prague and Glasgow..In 2017, we have planned workshops for Lucknow in India,  Cape Town in South Africa, Warsaw in Poland and in different cities of China.  In 2018 we are planning  workshops  for Rio de Janeiro and Sao Paulo in Brazil, Paris in France and in India and China.
