Richa’s research is “NON UREMIC CALCIPHYLAXIS” highly fatal and extremely rare disease of “ Non Uremic Calciphylaxis ”, which has a reported mortality rate of 81% within 6 months of diagnosis , which is much more than many of the stage IV malignancies. It is an ischaemic vasculopathy characterized by the deposition of calcium within the media of small and intermediate dermal vasculature which can lead to epidermal ischaemia , ulceration and necrosis. It is usually seen in end stage kidney disease patients but i am working on that disease that develops in non kidney disease patients.

My work at the Nowicki lab at Duke University involved exploring the effects of categorical colour perception on mate choice in zebra finches. Realistic animations of videos of singing males were used in a two-choice experimental set-up to determine the preference of females under highly controlled conditions. Data were also collected to investigate the role of luminance in categorical colour perception in these birds. I also picked up fieldwork techniques such as misnetting and banding/ tagging, essential for an ecologist. In addition, birdcare (handling and rearing of bird populations in the lab) comprised a major part of my learning experience in the lab. I was also exposed to the rich field of bird-song, another primary area of research in the lab. My work would help further current understanding of how animals perceive the world and influence our knowledge of the evolution of colour-based signals in the animal kingdom.
“My project involves using data science in order to obtain models for aerodynamic prediction, which are trained using CFD and physical experiment data. These models can then predict flow fields and forces on bodies at a fraction of the time and cost taken by CFD and physical experiments. The present focus is on achieving this through the use of Convolutional Neural Networks.”

I worked on designing an “Evaluation Board for a non-magnetic CMOS based Circulator”. Non-reciprocal devices such as circulators have immense application in communication, radar, imaging and sensing. Such devices are mostly made from magneto-optical materials which are bulky, expensive and they cannot be easily integrated on a CMOS based integrated circuit.
Recently, non-magnetic CMOS based circulators have been demonstrated and they have a lot of potential.
The designed evaluation board, which provides an interface to use this new circulator, will be sent to other research groups so that they can easily experiment with the circulator for new applications.

I did my summer research internship at the University of Illinois at Urbana-Champaign under the guidance of Prof. Chad Rienstra. My project was on the quest of searching lattice structure and dynamics of celebrated antifungal drug Amphotericin-B (AmB) and its interaction with Cholesterol and Ergosterol. The motivation of this project was to understand the working mechanism of the drug inside a cell. Since AmB is also a nephrotoxin and kills good cells (presumably by binding with Cholesterol) besides killing fungal cells (binding with Ergosterol), a modified structure of AmB for targeted functionality is necessary. I used solid-state NMR data of AmB from various experiments and conducted molecular dynamics simulations with restraint inputs from the NMR NOE data. I’m currently continuing to contribute to the project by doing Density Functional theoretic calculations to understand UV-Vis spectrum of the AmB lattice.

The topic that Rhaul is studying is Rhodopsin Biosynthesis and Disc Formation in Rod Photoreceptor cell Description: Photoreceptor cells are a specialized type of neuron found in the retina that absorb and convert photons into electrical signals. They are essential for initiating the phototransduction cascade, which ultimately leads to visual perception. There are two types of photoreceptors: rods and cones. Rods are located in the outer regions of the retina and allow us to see in dim light as well as dark conditions. Rhodopsin is the light sensitive visual pigment in rods that allows humans to see in these low light conditions. Cones, on the other hand, reside mostly in the central portion of the retina and allow us to perceive fine visual detail and color. Both rods and cones are comprised of an outer segment full of discrete membranous discs, an inner segment, a nuclear layer, and a synaptic terminal. My project focuses on understanding rhodopsin biosynthesis and disc formation patterns in rod outer segments (ROS). It is widely accepted that disc formation in mammalian rods follows a 10-day cycle and light exposure increases disc phagocytosis at the apical end and increases lipid production at the basal end. Phagocytosis and degradation of ROS ensures functional integrity of the photoreceptor cells and other retinal cells. There are several factors, such as genetic or environmental factors, that can cause photoreceptor degeneration and eventual vision loss. Currently I am exploring how varying light conditions impact ROS renewal and rhodopsin incorporation into discs. Using a transgenic mouse that has a fluorescent marker attached to rhodopsin, I aim to understand the pattern of disc formation, rhodopsin biosynthesis in ROS, and the degenerative effect of light. This project can provide insight on how light exposure affects photoreceptors structure and function, which plays a key role in the visual process.

Sibendu is studying the ffective SINR measurement for wifi OFDM PHY layer abstraction. Actually present PHY layer abstraction has a default AWGN channel so we have a constant frequency independent SINR but to avoid interference and multi path fading we go for OFDM where a number of subcarrier frequency bands used to send parallel bit stream. So here SINR will be different in each frequency band so we get a SINR vector that we are trying to map in a single SINR by EESM and MIESM algorithm. The entire implementation will be done in NS3 where the SISO (Single Input Single Output) model exist so from the SINR vector got from MIMO model we will have a single SINR so that it can be equivalently fitted in that SISO.model

I was involved in the project HELIX (High Energy Light Isotope eXperiment). It is a balloon-borne experiment designed to measure the chemical and isotopic abundances of light-cosmic ray nuclei from ~200 MeV/nucleon to ~10 MeV/nucleon. It is expected to fly in Antarctica in December, 2020. I tested the Silicon Photomultipliers which are used in fabrication and testing of the time-of-flight detector systems. The IV characteristics were made to know about their operating voltage. Thermistor calibration and vacuum testing were done to know their behavior. SiPM assembly was mounted on scintillator bars for the assembling into the overall HELIX instrument.”
Sai Sinhu is working on Biosensors for small molecules based on Transcription Factors. They have transcription factor gene and a GFP transformed into a bacterial cell. So when the transcription factor goes and binds to promoter of GFP , the GFP is repressed. When the small molecule binds to transcription factor, it leaves the promoter making space for RNA polymerase to bind and GFP is expressed. So this GFP on Off helps us to sense how much small molecule is produced in the cell. I am checking which promoter for transcription factor will give us a good on-off signal. So they selected promoters which have diverse distributed protein production units and planning to transform them into bacterial cells and see how the GFP on off works.
