Lab Members

Postdoctoral Scholars

Angelica Hagsand, Ph.D.

Dr. Hagsand earned her Ph.D. at the University of Gothenburg, Sweden in Psychology in June 2014, where she is a member of the research units Criminal, Legal, and Investigative Psychology (CLIP) and Addiction Psychology: Experimental and Clinical research (APEC), and the Center for Education and Research on Addiction (CERA). Her research interest concerns both the acute effects of alcohol on memory and behaviour, especially in a eyewitness context, but also factors involved in long-term alcohol dependence (e.g., genes, psychobiological factors, signal substances, the reward pathway in the brain).

Dr. Hagsand was awarded a 3-year postdoctoral research fellowship by the prestigious Swedish Research Council. In collaboration with our Investigative Investigative lab, she is currently examining the importance of system variables in alcohol’s effect on witnesses memory and how the legal system views those witnesses.


Graduate Students

Michelle Pena

Michelle received her B.S. in Psychology from FIU in 2013 and her M.S degree from FIU in 2017. She is primarily interested in conducting research on investigative interviewing techniques used on vulnerable witnesses and the effects of cognitive bias in investigative interviewing and forensic examination contexts.

Christopher Altman

I am a fourth-year doctoral student in the Legal Psychology Graduate Program at FIU. I received my B.S. in Psychology from the University of Pittsburgh at Greensburg (2012) before earning my M.S. degree at Ball State University (2014). My research interests are vulnerable witnesses and how interviewing affects lineup identifications. Currently, I am examining how elevated levels of alcohol (>.08) affect eyewitness memory. Those interested in my research can contact me at

Andrea Wolfs

Andrea received her B.Sc. in Psychology and M.Sc. in Psychology and Law from Maastricht University. During her undergraduate program she developed an interest in witnesses, and for her Master’s thesis, she conducted research in which the Concealed Information Test (originally a detection deception technique) was used for eyewitnesses. Now she is a first-year PhD student in the Legal Psychology program at FIU. Her main interests include eyewitness interviewing and identifications, and she is currently working in Dr. Schreiber Compo’s lab on Dr. Hagsand’s study involving alcohol and interviewing witnesses.
