Nancy Amato’s Research Research Group 12+ graduate students 2-4 undergraduates during the academic year usually 2-4 undergraduates for summer internships (not all from TAMU) Research Topics Motion Planning, Computational Biology, Robotics, Animation, VR Parallel & Distributed Computing, C++ Libraries, Performance modeling Computational Science (Chemistry, Geophysics, Neuroscience, Physics) Undergraduate Research Projects recent projects from all the above areas usually work in small group with me, an advanced graduate student, and possibly another undergraduate many projects lead to publications in international conferences and journals
Motion Planning start goalobstacles (Basic) Motion Planning: Given a movable object and a description of the environment, find a sequence of valid configurations that moves it from the start to the goal. Example: The Alpha Puzzle Objective: Separate the two tubes, one is the ‘robot’ the other is an ‘obstacle’
Soccer Ball: 31 dofPolyhedron: 25 dof Hard Motion Planning Problems: Highly Articulated (Constrained) Systems Digital Actors Closed chain constraint Paper Folding
Hard Motion Planning Problems: Group Behaviors for Multiple Robots Traversing a Narrow Passage
Hard Motion Planning Problems Computational Biology & Chemistry Drug Design - molecule docking Protein Folding – find folding pathways

Computer Graphics Graphics shape modeling and solid modeling Interactive graphics modeling systems Graphics data structures and algorithms Undergraduate student participation: development, implementation, and testing of interactive graphics modeling systems
Jennifer Welch’s Research Research Group 5 graduate students 2 undergraduates 1 post-doctoral fellow Research Topics – Theory of Distributed Computing Mobile Ad Hoc Networks Metamorphic Robots Randomized Distributed Data Structures Undergraduate Research Projects involve theory and/or implementation, as student wishes closely integrated into research group projects can lead to publications
Mobile Ad Hoc Networks l MANET: links form and disappear as nodes come into and go out of each other’s wireless communication range l Investigating design of fault-tolerant algorithms and services Undergrad projects: algorithm development and simulation for clock synchronization, leader election, group communication.
Metamorphic Robots l How to get a collection of homogeneous interlocking robots to change their global shape Undergrad project: algorithm develop- ment, correctness proof, and simulation for handling obstacles.
Distributed Data Structures l Develop useful and rigorous specifications of DDS’s with probabilistic behavior l Find efficient algorithms to implement the specifications l Identify classes of distributed applications that can tolerate probabilistic behavior Undergrad projects: simulation of distributed linear algebra applications; simulations of algorithms to implement a shared stack.
