Awardees - CalSEED

Gridware was founded with the belief that the passion and agility of start-up innovations will play a decisive role in the modernization of our power grid. As devastating wildfires hit communities and millions of hectares of land more frequently and more violently, a critical step in addressing this challenge and the many other challenges of climate change is the ability to bring together experts, grid operators, regulators and innovators to solve them together. To do this, we need a solution that is dynamic and deployable. A solution that is predictive and precise. A solution that stays ahead of the problem rather than catching up. We are building Gridware to be that solution.

Transfer Learning for Advanced Building Controls

Location: Berkeley, CA

Supervisors: Tianzhen Hong, Building Technology and Urban Systems Division

Machine learning (ML) models have demonstrated excellent performance in optimizing building controls for energy efficiency and demand flexibility. However, transfer learning is a challenge in ML based building controls as a very limited number of buildings have adequate and good-quality data for training and validating ML models. Transferring these ML models to other buildings with limited data will require effective algorithms which are structured in a way that bridges two different buildings capturing their common and different characteristics (e.g., energy system type, operation strategies, climates). The intern will help review transfer learning algorithms and choose a few to test for reinforcement learning based building controls.  One intern is needed.

The intern is required to have knowledge of machine learning especially reinforcement learning and understand transfer learning. It is a plus if the intern knows how to use popular ML toolkits for Python coding and testing ML models. The intern will be part of a project team presenting and discussing progress weekly. Depending on the outcomes, there is a potential for the intern to contribute to the writing of a journal article. 

Work location: LBNL main campus (assuming COVID-19 is over by the summer - if not then some/all work may become remote).

Working period: 8 weeks

Preferred start date: flexible start from mid May to early July of 2020.

Solid-State Battery Intern

Location: Berkeley, CA

Supervisors: Gao Liu, Applied Energy Materials Group

The Applied Energy Materials group at ESDR is looking for one materials sciences intern. The intern will perform experimental materials research on solid-state battery for electric vehicle applications. The intern will synthesis new solid-state ion conductors, fabricate batteries based on those ion conductors, and testing the battery cells. 

This is an experimental internship.

Work location: LBNL main campus in Building 70 (assuming COVID-19 is over by the summer - if not then some/all work may become remote). 

Preferred start date: beginning of summer. 

New Insights into Advanced Membranes for Energy Applications

Location: Berkeley, CA

Supervisors: Gregory Su

New materials with tailored functionality are needed for technologies renewable energy technologies. Membranes enable the selective transport of specific species are critical components in these technologies, for example, the proton conducting membrane in a hydrogen fuel cell. Membranes made of polymers are attractive due to their tunable chemistries and favorable mechanical properties. However, we still need to better understand how molecular architecture dictates the nanoscale assembly of polymer molecules and ultimately membrane performance. This internship will focus on probing the nanoscale structure of membranes using unique experimental X-ray tools coupled with simulations and other characterization methods to gain new insights into membrane structure-property relationships. The work will involve working closely with research groups at Berkeley Lab and take advantage of Berkeley Lab's world-class facilities, including the Advanced Light Source and the Molecular Foundry.

Number of interns required: 1

Work location: LBNL main campus (assuming COVID-19 is over by the summer - if not then some/all work may become remote). 
Preferred start date: dates flexible during the summer of 2021

Bioenergy Quantum Sensing

Supervisors: Benjamin Gilbert

We seek one motivated undergraduate intern to contribute to the development of a new chemical imaging method to optimize biofuel production in bioreactors. The candidate will work with a multidisciplinary team of scientists in Earth & Environmental Sciences and Biosciences Divisions at Lawrence Berkeley National Laboratory (LBNL). Our groups are collaborating on using quantum sensing and complementary methods to study microbial metabolic processes, ultimately for the in-situ observation of single-cell biochemistry. Depending on background, and onsite or virtual intern, the candidate will design optical, microfluidics or microwave instrumentation, develop python software for data acquisition, or acquire and process chemical imaging data from microorganisms using a diamond-based quantum sensor, a confocal fluorescence microscope or a Raman microscope. 

Motivated candidates from the core STEM fields will be considered, and preference will be given to the ones with relevant experiences and skills.

Internship positions and descriptions will be announced soon. Check back for updates.

Takachar is an MIT spinout company with a test site in Berkeley, CA. The company's vision is to expand the amount of biomass (crop and forest residues) economically converted into useful products (we turn trash into cash). Our impacts include income and job creation in rural areas, as well as mitigation of CO2 emission and air pollution associated with conventional open-air biomass residue burning. If successful, this could also potentially reduce the risk of catastrophic wildfires.

(1 internship, 1 intern will be placed) 

Project Engineer (AKA Firebreather)

Location: Berkeley, CA

Supervisor: Kevin Kung

In summer 2021, we will be building and testing an internal prototype. We are seeking one project engineer to coordinate this effort. The engineer will assist in testing the prototype, first in a laboratory setting, and also potentially in the field. In the latter stage of the project, you should be prepared to work in a rural environment (in California) under resource-constrained settings.


Prior experience with SolidWorks, design for manufacturing, control systems, and reactor testing will be helpful. A project website (if you have one) will help us gauge your experience.
