Apatite to Zircon, Inc.

Mapping for Microscopes: Automatic Processing of Apatite Images

Liaisons: Ray Donelick P15, Ravi Kumar ’14
Advisor: Zachary Dodds
Students: Kaya Woodall (PM), Justin Jones, Kathleen Schaefer, Richard J.T. Booth

Apatite to Zircon is a geology company that specializes in sediment analysis for determining a region’s geological history. A majority of the geologists’ time is spent at the microscope, manually searching for crystals to be analyzed. To increase the flexibility of this process, we implemented a fully-automated system that captures in-focus images across an entire slide, which we then provide in a seamless, high-definition viewing environment. In addition, we also generate locations of suggested crystals of interest.

University of British Columbia

Design and Analysis of RNA Molecules with Diverse Folding Pathways

Liaison: Dr. Anne Condon
Advisor: Elizabeth Sweedyk
Students: Rachel Sherman (PM), Kennedy Agwamba (F), Sasha Heinen, Carson Ramsden

Artificially designed nucleic acid molecules with diverse folding pathways have many potential uses, from performing computations with biological material, to having therapeutic applications. However, designing molecules that behave predictably is challenging. Building on software that simulates a molecule folding, our software outputs statistics and graphics about potentially interesting structures in a molecule’s folding pathway. Researchers can use this software to test and modify new designs until they fold as desired. Additionally, we have analyzed a theorized molecule and proposed modifications to its structure.

Liaison: Terry Hudson
Advisor: Elizabeth Orwin
Students: Cody Crosby (TL-S), Mengyi Tao (TL-F), Weimeng (Stephanie) Kong, Eric Caldwell (S), Ana Villa (S), Thendral Govindaraj (F)

Genentech employs sterile lab scale bioreactors to engineer drug-based medical solutions. Typically, bioreactors are manually sampled to monitor their internal conditions and to ensure cell culture integrity. An automated sampling system was introduced to increase sampling efficiency and to reduce ergonomic risk. However, foreign contaminants compromised the sterility of the system. The Genentech Clinic Team has designed, built, and tested two distinct sterile barriers that will increase the reliability of the pre-existing automated sampling system.

The system has the potential to be a light, inexpensive, and robust vibration isolation system.

Engineering/Physics Clinic

HRL Laboratories

Optical Networks for Controlling Quantum Communication Systems

Liaisons: Dr. Thaddeus Ladd ’98, Dr. Danny Kim, Dr. Matthew Rakher, Dr. Nathan Jones
Advisors: Theresa Lynn, Qimin Yang
Students: Alexander Kendrick (TL-S), Luke St. Marie (TL-F), Paul Jerger, Fernando Ortega (POM), Kunal Menda (S), Nithya Menon (F)

One challenge in developing quantum communication technology is the rapid decoherence of stored quantum information. When information is stored in the state of a quantum dot, nanosecond- to microsecond-scale sequences of ultrafast laser pulses can theoretically preserve the state long enough for practical use. The objective of this project is to design, model, and evaluate optical networks to create these precisely timed pulse sequences. Using custom modeling tools, the team designed and simulated a network that should significantly reduce quantum-dot decoherence.

As cloud storage becomes more prevalent, greater demands for security and accessibility are placed on searchable databases. The goal of our project is to develop a scalable, efficient strategy for searching distributed, encrypted databases. Popular existing approaches were not designed with encryption in mind, leading to prohibitive overhead. We provide a proof of concept (via a well-documented API) of a sublinear encrypted search architecture by implementing and benchmarking our solution.
