About
Alexandra Bacula is a pioneering researcher at the intersection of expressive robotics, human-robot interaction, and movement psychology. Her work uniquely bridges performing arts and engineering, most notably through applying Laban Movement Analysis (LMA) to enable robots—from humanoids to aerial platforms—to convey recognizable character traits and emotions. Her foundational papers on character synthesis using ballet archetypes (11 citations) and character recognition via LMA (10 citations) demonstrate how robots can perform legible, emotionally resonant movements that laypeople and experts alike can interpret. Beyond artistic expression, Bacula has made significant contributions to industrial robotics, developing legible light communication systems for factory robots (7 citations each) that help human coworkers intuitively understand robot intent. Her research on multi-robot systems explores how group motion, timing, and spacing affect human perception—from social triangles to aggressive formations—revealing how incoherent or divergent motions influence functional and social interpretations. With over 50 total citations across her ten most-cited works, Bacula is shaping how robots move expressively in both social and industrial contexts, making her a leading voice in creating robots that are not just functional, but genuinely communicative and relatable.
