As mentioned by his collaborators Christo I. Christov and his former
Ph. D. student Andreas Wierschem, with deep theoretical insight he
guided the systematic numerical/computational and experimental
exploration of all possible features (collisions, wall reflections, and
other evolutionary aspects) of solitonic interfacial waves driven by the
Marangoni effect. The consequences of the discoveries have proven to
be of much value well beyond their interfacial hydrodynamics origin.
