Allan Ashworth is a researcher and a teacher in paleoecology at North Dakota State University who specializes in insects and their response to climate change. He was educated at the University of Birmingham, UK, where he was a student of Quaternary researchers Russell Coope and Fred Shotton. He has worked on Quaternary projects in several countries. Currently, he is studying full-glacial insect assemblages from the Lake Region of Southern Chile and from the Olympic Peninsula, U.S.A. Additionally, he works on Miocene-aged fossiliferous deposits in Antarctica where modern organisms evolved adaptations to cold earlier than they did in the northern hemisphere. He is also collaborating with a large group of scientists from around the world to develop the Neotoma Paleoecology Database. His research is featured in the film ‘Ice People’, the NOVA documentary ‘Secrets Beneath The Ice’ and in Science magazine. Fossil discoveries made in Antarctica are featured in articles in National Geographic and in the world press, and are recognized in the New Zealand Geographic Board citation for the Ashworth Glacier.

Zhengtang Guo is a research professor in the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGG-CAS) and also a professor in the University of Chinese Academy of Sciences (UCAS). His research interests are centered on the Cenozoic/Quaternary Geology, ranging from Paleoclimatology, Paleopedology, Biogeochemistry and human-environment interactions. He has particular expertise in exploring the climate information from the Neogene-Quaternary eolian deposits in China across a wide range of time scales. He and his colleagues extended the near-continuous loess-soil records in China from 8 Ma (million years) to 22 Ma that attest to the formation of the monsoon-dominated climate and inland deserts in Asia by the early Miocene due to the uplift of the Himalayan-Tibetan complex.Zhengtang served as the vice-president of the INQUA Commission on Paleoclimates (1995-2003), as a member of PAGES Scientific Steering Committee (1996-2001) and as a co-leader of PAGES’ Australasian Pole-Equator-Pole (PEP-II) international project (1999-2002). He is now a vice-president of the China Association of Quaternary Research (CHIQUA), an editor of Global and Planetary Change, and a deputy editor-in-chief of Science China: Earth Science. He was elected as academician of Chinese Academy of Sciences in 2013.
Thijs van Kolfschoten studied Geology and Biology and obtained his PhD in Palaeontology at the Institute of Earth Sciences, University of Utrecht (The Netherlands). After a research position at the Institute of Palaeontology, University of Bonn (Germany) he moved to Leiden University (The Netherlands) where he is working as Professor in Palaeozoology and Quaternary Biostratigraphy at the Faculty of Archaeology.
His main fields of interest are Quaternary mammals, biostratigraphy, palaeoecology and taphonomy. His palaeontological research focuses on continental deposits with an age that ranges from the Early Pleistocene until the early Holocene. A major research project is the study of the mammalian vertebrate fossils from a sequence exposed at Schöningen (Germany); a sequence that plays an important role in the debate on the late Middle Pleistocene climatic and faunal history. The Palaeolithic sites of Schöningen yielded a large amount of mammalian remains with features that indicate exploitation by Lower Palaeolithic hominins. The study of these features is also part of the current research project.
During the past decade, changes in Late Pleistocene and early Holocene ecosystems in Europe north of the Alps have been investigated in close collaboration with Russian colleagues; past projects are: The evolution of the mammalian fauna and flora in Western, Central and Eastern Europe during the Pleistocene – Holocene transition (25 - 10 kyr B.P.) combining well-dated flora and fauna data and The Collapse of the Mammoth Steppe ecosystem (COMSEC) investigating the disintegration of the Mammoth Steppe ecosystem at the level of faunal assemblages as well as at species level. Currently, studies on the Late Pleistocene faunal evolution focus on eastern Siberia.
Thijs was President of the INQUA Subcommission (now Section) on European Stratigraphy (SEQS) from 1995 to 2003, and he was President of INQUA Netherlands from 1999 to 2008 when he was the national Delegate representative at the INQUA International Council meetings in Durham (1999), Reno (2003) and Cairns (2007). He has been regional Editor (Europe) of Quaternary International from 2003 to 2015. In addition, he has been a member of SACCOM from 2003 to present, and Secretary of SACCOM from 2011 to 2015. He was member of the steering-committee of APEX (Arctic Palaeoclimate and its Extremes), which forms an umbrella programme for European Arctic palaeoclimate research. He was secretary of the IUGS Subcommission on Quaternary Stratigraphy, member of the scientific advisory board of Senckenberg Research Institute (Frankfurt, Germany) and the Centre of Archaeological Sciences (Leuven, Belgium).
Currently, Thijs van Kolfschoten is the director of a well-equipped laboratory for palaeozoological and archaeozoological studies at the Faculty of Archaeology, Leiden University and head of the Bioarchaeology Research Group.
Ashok Kumar Singhvi is currently working as a Honorary Professor and J.C. Bose National Fellow at the Physical Research Laboratory (Department of Space, Govt. of India), Ahmedabad, India. A physicist by training, he has close to four decades of experience in Quaternary Geochronology and Paleoclimatology. He is known for his fundamental work on luminescence dating of Desert Sands and has provided event chronologies for most deserts of the world. He suggested that different deserts responded differently and episodically, to same climate forcing. This implied the need for changes in conventional concepts. He has also worked on global dust sequences and demonstrated their episodic accretion to suggest fundamental difficulties in their correlation with marine and ice core records. He developed luminescence dating of pedogenic carbonates, fulgurites, carbonate, gypsum and volcanic ashes and has contributed extensively to the methodological development of this technique. He has contributed over 170 papers in peer reviewed journals, several book chapters and edited about 16 special issues of journals.
Singhvi has worked on the executive committee of the International Geosphere-Biosphere Programs's - PAGES (Past Global Changes) core project; Science Program Committee of the UN- International Year of Earth and was the co-leader of two International Geological Correlation Programs IGCP-349 on Desert Margins and Paleomonsoons and IGC-413 on Past and Future Evolution of Deserts. He is on the Editorial Boards of Quaternary Research (Associate Editor), Quaternary Science Reviews, J. Quaternary Science, The Holocene, Ancient TL, J. Earth Environment Mediterranean Archeology and Archeometry, Episodes and is a Member of the Senior Adv. Panel of Springer Encyclopedia of Quaternary Science.
Singhvi is a Fellow of Indian National Science Academy, The Third World Academy of Sciences and is a Life time Honorary Fellow of the Geological Societies of London and India. He was the Chair Indian Committee for IUGS and INQUA and Chairs, Indian Ministry of Earth Sciences' funding committees for Geosciences and for Paleoclimates. Singhvi has been a recipient of several recognitions'/awards, including the Geological Society of America's Farouk El Baz Award for Desert Sciences.
Margaret Avery is a palaeoecologist with an archaeological background whose long-time interest is exploring the multi-facetted information potential of micromammalian prey of barn owls. Arising from this has been the main thrust of her research, contributing to our knowledge of the environmental background to human biological and technological evolution. To this end she has worked on material from all of the important archaeological sites in South Africa as well as early hominid sites such as Sterkfontein and Swartkrans, and sites in Zambia. Another aspect has been applying information to global change studies and the assessment of human impact on the environment. Complementary studies of modern material, besides being important in their own right, help inform taphonomic analyses of fossil samples.
Margaret is a Fellow and Vice President of the Royal Society of South Africa, and a Past President of the Southern African Society for Quaternary Research. She serves on the ICSU South African National Board and ex officio on the South African National Committee for INQUA. She was also Secretary-General of the XV INQUA International Congress held in Durban in 1999. She has been Editor of the South African Archaeological Bulletin and Transactions of the Royal Society of South Africa.
