David Goggin

PhD Candidate

I graduated from Angelo State University (Texas) with a B.S. in chemistry in May 2016, began my PhD in the Chemical and Biological Engineering Department at Mines in August 2016, and joined Dr. Joe Samaniuk’s lab as a PhD student in January 2017.

My research is focused on linking the dynamics, structure, and properties of thin-films of 2D materials (graphene, h-BN, MoS2, etc.) formed at fluid-fluid interfaces. Two-dimensional particles have the ability at fluid-fluid interfaces to interact laterally and form large-area films like other colloidal particles, but these platelet-like particles also exhibit a unique “stacking” dynamic that can lead to multi-layered structures. Understanding how 2D materials assemble into a given film structure and correlating functional film properties (conductivity, transparency, etc.) with film structure will allow us to engineer thin-films of such materials with desired functional properties for future applications in next-generation optoelectronic devices.

About me: I have completed my Bachelor’s Degree in Chemical Engineering from Institute of Chemical technology-Mumbai, India. Currently I am pursuing my Doctoral degree in Chemical Engineering under supervision of Dr. Samaniuk. I joined his soft matter and interfaces research group in Spring 2017.

Research: My research area focuses on characterizing microrheology of complex viscoelastic fluids. Conventionally, passive particle tracking which uses probe’s Brownian displacements to back out local rheological properties is considered as one of the simplest approach. However, it is restricted to relatively low modulus materials due to its limitations in resolving the displacements in higher  modulus materials. My work aims at developing new active microrheological technique in the form of electromagnetic tweezers to overcome this limitation of passive method. The goal is to artificially enhance the restricted Brownian motion of probe such that the displacements are detectable. Our approach is suitable for both bulk and interfacial microrheology with applications in materials like biological cells, scaffolds, complex 3D and 2D materials, etc.

B.Sc, Chemical Engineering, Oregon State University, 2017

Ph.D student in Dr. Samaniuk’s Soft Matter & Interfaces group in the Department of Chemical & Biological Engineering since Spring of 2019.

Research Interests –

Currently working on the flowability of soil suspended in non-Newtonian fluids. The project focus is to link soil-scale interactions to bulk rheological properties under tunneling conditions.

Visiting PhD Student

Fernando’s home institution is the Universidad de los Andes – Colombia where he is primarily advised by Dr. Diego Pradilla and Dr. Oscar Alvarez. He received a Fulbright scholarship to study in our lab at CSM, during which time he has performed experimental work with asphaltenes. The focus of his project is to link molecular-scale behavior of asphaltene molecules at fluid-fluid interfaces with the bulk stability and rheology of asphaltene-stabilized oil and water emulsions.

Mines Undergraduate Research Fellow

I am a materials engineer planning on pursuing a career conducting research on the properties and processing of functional materials, particularly ceramics. Currently, I am working on my bachelor’s degree in metallurgical and materials engineering, but I plan to pursue a higher degree I materials science (Masters and/or Ph.D.). 

I have worked with the interfacial rheology group for a year where I have been designing an experiment to refine heptane for interfacial rheology and thin film graphene design. Throughout the process, I have identified variables and methods for the purification of heptane past the highest HPLC grades.
