I am looking for a highly motivated PhD student to help coordinate and do research in a project related to large scale patterns of activity patters of mammal species (mostly terrestrial, non-volant mammals) and how do these are relevant to community structure. Specific research questions are flexible within this area and will be dependent on specific research interests of the student within this academic topic. The basis of analyses will be data derived from camera trapping that will be evaluated in a macroecological comparative context. Thus, a student with highly quantitative and integrative mindset is an asset and one well suited for this project. Support for this PhD position will be through a Research Assistantship starting in Fall 2023. For consideration, please email Dr. Ivan Castro-Arellano ( a SINGLE PDF that includes: letter of interest, resume, unofficial transcripts, and contact information for 3 references. The letter of interest must explain your experience relevant to the minimum and preferred qualifications and how the position would fit with your academic and professional goals. Letters that do not address these points explicitly will not be considered. Please include “PhD Assistantship Application – Activity Patterns” in the subject line of that email. Materials will be reviewed as received and the position filled upon finding a suitable applicant. There is no need to submit an official application through the university until the selection of a candidate is complete. The selected candidate will need to be able to apply to the PhD program deadline of January 15, 2023 (see below links for the application requirements).
