Visiting Students

Many graduate students from other institutions in the U.S. and abroad have visited the AMNH Arachnology Lab in the past, often funded in part by the AMNH Small Grants program (Annette Kade Fellowships, Collections Study Grants and Theodore Roosevelt Memorial Fund). If you are interested in applying for small grants to visit the AMNH, please visit the Richard Gilder Graduate School.

Ricardo Botero-Trujillo Ricardo Botero-Trujillo
Doctoral fellow, Division Aracnologia
Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" - CONICET, Argentina
(Theodore Roosevelt Memorial Grant)

Ricardo Botero Trujillo earned his biology degree from the Pontificia Universidad Javeriana, Bogotá. While an undergraduate student, he became interested in arachnids and started working on scorpions from his native country, Colombia. Gradually, hooded thick-spider (order Ricinulei) and sun-spiders (order Solifugae) became part of his research interests. After a 5-year period working in the pharmaceutical industry, Ricardo moved to Buenos Aires, Argentina to start his Ph.D. His doctoral thesis consists of a taxonomic revision and phylogenetic analysis of the South American sun-spider family Mummuciidae. After being awarded a Theodore Roosevelt Memorial Grant, Ricardo visited the AMNH to study the collections of the groups he works on.
