The “Surfactants in Solution” symposium series was initiated in 1976, when it was first held in Albany, New York, under the chairmanship of Dr. Kash Mittal. Two more meetings were held in the USA (Knoxville and Potsdam) before the symposium became truly international: Lund (1982), Bordeaux (1984), New Delhi (1986), Ottawa (1988), Gainesville (1990), Varna (1992), Caracas (1994), Jerusalem (1996), Stockholm (1998), Gainesville (2000), Barcelona (2002), Fortaleza (2004), Seoul (2006), Berlin (2008), Melbourne (2010), Edmonton (2012), Coimbra (2014), Jinan (2016), Norman (2018) and Lublin (2022). These symposia allow academicians and scientists from industry to present their work in basic aspects of surfactants and interfacial science and also meet people and network with their peers working in these all important areas. The next edition of the conference will be held at the K. K. Birla Goa Campus of Birla Institute of Technology & Science (BITS) Pilani. We look forward to hosting you in Goa in June 2024 and to make SIS2024 a memorable scientific and cultural experience.
