Mechanical Engineering

Sergio Pellegrino studies deployable composite shells for large space solar arrays, where lightweight construction and compact storage are essential. A design explored in Caltech's Space Solar Power Project uses slender cylindrical longerons formed from two circular-arc flanges bonded along an edge. Laminates thinner than 0.1 mm permit tight packaging but make bending behaviour sensitive to local geometric imperfections. The talk examines how the size, shape and distribution of those imperfections explain nonlinear moment–rotation measurements and determine overall bending stiffness, connecting detailed structural analysis with prototype observations. Online via Zoom. Tuesday 29 September 2026 at 12:00 EDT (America/New_York; UTC−4). Organized by ASCE Engineering Mechanics Institute — Stability Committee. Researchers, practitioners and students can use Register for Zoom Link on the organizer's page; the event-specific form requests contact and affiliation details. Attendees must acknowledge the organizer's prohibition on unauthorized recording, transcription and meeting-assistant bots. Pellegrino is a professor at the California Institute of Technology.

Gang Chen delivers MIT.nano's annual Dresselhaus Lecture, drawing on research that spans electron and phonon transport, thermoelectric energy conversion, microelectronic thermal management, desalination and data-center cooling.

The Soft Robotics Lab seeks postdoctoral researchers working on compliant robotic systems, biohybrid actuators, dexterous manipulation, robot learning or embodied-AI simulation. Researchers will develop and experimentally validate systems, publish findings and co-supervise students. The full-time Zurich appointment starts with a one-year contract, renewable annually. Applications are reviewed as they arrive until 30 November 2026; the start date is negotiable.
