I value a positive attitude, creativity, and the eagerness to learn over grades and exam scores. A commitment to our research team requires hard work, self-sufficiency, an ability to solve problems, and to work as part of a collaborative team.

I expect students to work diligently in the lab or field and communication about progress and set-backs is one of our highest priorities.

In return, I am dedicated to training and mentoring students through the process of research, graduate school, applying to grant and career opportunities, publishing, and becoming an independent scientist and contributing member of the scientific  community.

Dr. Catherine Hulshof (PI)

Dr. Hulshof is a tropical ecologist. She studies patterns of diversity across space from tropical to temperate latitudes and through time as ecosystems respond to long-term disturbances like climate change.

Curriculum vitae

Allyson Richins

Allyson is a Master’s student at Virginia Commonwealth University. She is studying plant and pollinator diversity in a serpentine savanna in the eastern United States and the effects of disturbance and recovery of plant and pollinator communities post deer-exclusion.

Ramon Agosto Diaz

Ramon is an ecologist trained in Puerto Rico. His expertise of the flora and fauna of the island keeps our lab and field projects functioning smoothly.

Luis Velazquez Roman

Luis participated in the Luquillo LTER NSF-REU program Puerto Rico and investigated the diversity and distribution of butterflies. He is now continuing an independent research project in the lab relating species distribution models and phenotypic variation of butterflies.

Mariangeli Echevarria Ramos

Mariangeli has been working in the lab on an independent research project relating phenotypic variation of wing color and size in the non-migratory Puerto Rican monarch in montane and coastal regions. She also made important contributions to our large Puerto Rican Lepidoptera Digitization project.

Dayneris Aparicio Jimenez

Dayneris studied the effects of low oxygen levels on benthic macrofauna in the bay of Cienfuegos, Cuba before beginning her Master’s at UPR-Mayagüez. She is now studying the effects of Hurricane Maria on the recovery and resilience of butterfly populations in Puerto Rico.

Claudia Garnica Diaz

Claudia previously worked in the páramo of Colombia before beginning her Master’s at the UPR-Mayagüez. She is studying plant functional diversity of serpentine soils across mountains in Puerto Rico to better understand how these unique systems may be affected by ongoing and future climate change.
