Neutrinos are abundant subatomic particles that are famous for passing through anything and everything, only very rarely interacting with matter. About 100 trillion neutrinos pass through your body every second. Now, scientists have demonstrated that the Earth stops energetic neutrinos-they do not go through everything. These high-energy neutrino interactions were seen by the IceCube detector, an array of 5,160 basketball-sized optical sensors deeply encased within a cubic kilometer of very c...

ESA's first Earth observation satellite was launched on 23 November 1977. When the first Meteosat satellite took its place in the sky, it completed coverage of the whole globe from geostationary orbit and laid the foundations for European and world cooperation in meteorology that continues today. Weather - and particularly extreme weather - affects everything we do. Being able to see the whole disc of Earth allows forecasters to see developing weather systems, as well as working out wind spee...

Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides. Based on a 2016 study using data from NASA's Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness. The lava on the dayside would reflect radiation from th...

A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO's unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO's Extremely ...

    GRADUATE RESEARCH

    I began my graduate work in Michigan Tech’s Ion Space Propulsion (ISP) Lab during the fall of 2010. My research interests include electrospray thrusters, field emission electric propulsion (FEEP), in situ field visualization, and ionic liquid ferrofluids. My research focus is in electrospray propulsion, specifically needle and capillary electrospray thrusters. These thrusters are highly efficient relative to others space propulsion devices.  They use an electrostatic field to emit ions and droplets of a propellant through the principle of electrostatic extraction. Hundreds of ionic liquids have been or are being used as propellants, including EMI-BF4 and EMIM-NTf2, the propellants used primarily in the ISP Lab.  In the spring of 2011 I constructed a glass capillary colloid thruster and was able to collect a mass spectrograph using an ExB filter of an electrospray beam using EMI-BF4 as the propellant. The measurements proved that a simple inexpensive diagnostic tool could be used to accurately measure basic beam characteristics of electrospray devices.

    From 2012 to 2014 I investigated methods of visualization the electric fields that are necessary to produce the electrospray beams in these devices. One method used a grid of lines placed beneath a biased sharp solid tip needle within a scanning electron microscope (SEM). The SEM electron beam was deflected by the needle and interacts with the grid of line in such a ways that the resulting image has “contour” lines correlating to the spatial electric field strength. A similar method within a transmission electron microscope (TEM) uses a Mollenstedt biprism placed downstream from an electrospray emitter and a technique called electron holography, which is used to extract the spatial electrostatic potential from the phase shift of the waves caused by the biprism. I was able to visualize an ionic liquid electrospray in-situ, results of which I presented in the summer of 2013.

    I am a recipient of the 2013 NASA Space Technology Research Fellowship which funds my doctoral research in ionic liquid ferrofluid electrospray studies using time-of-flight mass spectrometry. Consequently, in 2014 I began investigating the spectral mass composition of an EMIM-NTf2 ionic liquid ferrofluid (ILFF) electrospray beam that is emitted from a capillary needle and the Rosensweig instability. Using a Rosensweig instability for electrospray is a novel approach to satellite propulsion developed by the Isp Laboratory. Past electrospray propulsion devices require time-extensive, expensive and/or fragile structures as emission sites; the Rosensweig instability provides peaks within seconds of an applied magnetic field, and can regenerate if damaged. Understanding how these differ from other electrospray propulsion devices will determine how beneficial they can be to the field. In completing this research, I have garnered extensive experience using time-of-flight mass spectrometers, electrospray diagnostic tools (Faraday cups, QCM, steering lenses), as well as the design and construction of actively-fed capillary electrospray systems using multiple propellants.

    PROFESSIONAL/RESEARCH EXPERIENCES

    As an undergraduate I was involved in Michigan Tech’s Aerospace Enterprise where I served as the project manager for the High Altitude Autonomous Research Platform (HAARP) glider and Photogrammetry Small UAV project teams. I also worked on the design and fabrication and testing of the UAV airframe.  This included computer-aided modeling, computational fluid dynamics simulations, and finite element analysis to ensure the designs fit our sponsor’s requirements.

    Also during my time as an undergraduate I completed a program called Pavlis Institute for Global Technological Leadership.  This involved 4 years of coursework and project work, including a 2009 facilitated a research project on human sanitary problems in Ghana, Africa.  A six-week, in-country study was done during the summer of 2009, which led to the construction of a community center the following summer. My time with the institute concluded with our project team leading a high school Summer Youth Program (SYP) on leadership and teamwork.

    From May to August 2008 I worked at Woodward as a Test Engineering Intern. During the internship I ran procedural tests on three GE Healthcare pneumatic servo controller test stands to diagnose a problematic servo controller. I also created hydraulic and pneumatic system drawings of 15 test stands, documented all Electronic Test Stands (ETS) and assessed future viability, and formatted new and current test computers with advanced setup and company programming.
