Francisco Mauro Gutierrez

(FERM, Temesgen Hailemariam)

Francisco is a visiting researcher from Spain, whose main research objective is finding suitable and efficient methodologies for forest inventories assisted with remotely sensed auxiliary information. Within this broad topic, he is specially dedicated to applications of Small Area Estimation methods to forest inventories that use LiDAR as auxiliary information to derive reliable estimates for forest attributes in the BLM Owned lands of Southwestern Oregon. His personal interests include cooking, fishing, coffee, watching movies, and basketball.



Gerald Page 

(FES, Chris Still)

Dr. Page hails from Australia, and has been a visiting researcher at OSU since 2017. He is a physiological ecologist who studies how plants use water and energy by combining traditional ecophysiological techniques with novel imaging methods including near-surface thermal and hyperspectral remote sensing. Gerald is particularly interested in understanding how plants survive in challenging environments. For example, how do trees cope with prolonged drought? What about infection by disease? Prior to coming to OSU, Gerald completed his PhD. at The University of Western Australia with Dr. Pauline Grierson and was a postdoc at Washington State University Vancouver with Dr. Kevan Moffett.

Martín López Aguilar

(FES, John Alexander)

Martín is an undergrad student from the University of Guadalajara located in Jalisco, Western Mexico, finishing his studies in Natural Resources and Agriculture, with a focus on bird conservation and their habitats. He has also been involved in different areas of natural resources studies, such as soil conservation and forestry. 

Martin is participating in an internship with Dr. John Alexander (FES Dept) at the Klamath Bird Observatory (KBO). Martín chose to come to KBO because it is one of the best organizations that train people to do bird studies with the highest level of ethics and technics. KBO also provides the opportunity to become certified as bird banders or trainers with the North American Banding Council, the institution in charge of bird banding ethics and guidelines.


Sergio Gómez Villaverde

(FES, John Alexander)

Sergio graduated as a biologist from the Universidad Autónoma Metropolitana Unit Xochimilco (UAM-X) in Mexico City in 2010. Previously, he has worked at banding stations in North, Central and South America, and he is now leading bird banding courses in Mexico to share his knowledge with others with the intent to promote ethical and responsible work in bird banding stations. Sergio's interests lie in bird conservation and research, and fostering a relationship in sustainability with the indigenous communities of Mexico. He has been part of his own project with a Mixteco community in the mountains of Oaxaca, sharing information of the fauna, scouting the habitat looking for birds and the memories and histories of the people who own these lands. This project aims to promote the conservation of their shaded coffee plantations, the native forests, the language and the ancient knowledge of the flora and fauna.

In 2016 he acquired his title as NABC Certified Bander. He is currently participating in an internship with Dr. John Alexander (FES Dept) at the Klamath Bird Observatory to become a NABC Certified Trainer.
