into developing strategies, which are based on receiving a 'natural' language message, that look at developing algorithms to detect if an ET signal has intelligent-like structure and if so, then how to decipher its content. Author of many papers in this area and a contributor to SETI's book on interstellar communication. Other contributions include message design and construction; member of: International Academy of Astronautics, SETI Permanent Study Group; International Task Group for the Post-detection identification of unknown radio signals. Laurence Doyle (SETI Institute): studies animal communication, and has developed statistical measures of complexity in animal utterances as well as human language. Stephane Dumas: developed Cosmic Call messages, as well as a general technique for generating 2-D symbols that remain recognizable even if corrupted by noise. Yvan Dutil: developed Cosmic Call messages with Stephane Dumas. Paul Fitzpatrick (MIT): developed CosmicOS system based on lambda calculus Brian McConnell: developed framework for algorithmic communication systems (ACETI) from 2000 to 2002. Marvin Minsky (MIT AI researcher): Believes that aliens may think similarly to humans because of shared constraints, permitting communication. First proposed the idea of including algorithms within an interstellar message. Carl Sagan: co-authored the Arecibo message and was heavily involved in SETI throughout his life. Douglas Vakoch (METI): editor of Archaeology, Anthropology, and Interstellar Communication, a 2014 essay collection on CETI. Alexander Zaitsev (IRE, Russia): composed Teen Age Message with Boris Pshenichner, Lev Gindilis, Lilia Filippova, et al., composed Bilingual Image Glossary for Cosmic Call 2003 Message, Scientific Manager of transmitting from Evpatoria Planetary Radar the Cosmic Call 1999, the Teen Age Message 2001, and the Cosmic Call 2003, Scientific consultant for A Message From Earth project. Michael W. Busch: (Lone Signal) created the binary encoding system for the ongoing Lone Signal hailing message. Jacob Haqq Misra: (Lone Signal) is the chief science officer for the ongoing Lone Signal active SETI project. Interspecies communication Some researchers have concluded that in order to communicate with extraterrestrial species, humanity must first try to communicate with Earth's intelligent animal species. John C. Lilly worked with interspecies communication by teaching dolphins English (successful with rhythms, not with understandability, given their different mouth/blowhole shapes). He practiced various disciplines of spirituality and also ingested psychedelic drugs such as LSD and (later) ketamine in the company of dolphins. He tried to determine whether he could communicate non-verbally with dolphins, and also tried to determine if some extraterrestrial radio signals are
