We are seeking a candidate to design and build a fully automated cloud-based inventory and research data management system powered by Google Sheets and Google Apps Script Automation. The goal is to create a system that supports multilevel data management, including institution-wise, project-wise, and investigator-wise data segregation, with real-time dashboards and auto-updating sheets.
The candidate will be responsible for developing a Dynamic Data Dashboard and Google Sheets Database System that enables seamless automated data entry, routing, and visualization for research and inventory management. The system should ensure data is automatically categorized under respective institutes, principal investigators, and projects, supporting efficient and organized data handling.
Keywords: Google Sheets Database System, Dynamic Data Dashboard, Automated Data Entry and Routing, Multilevel Data Management, Google Apps Script Automation, Institution-wise Data Segregation, Project-wise Data Handling, Cloud-Based Inventory System, Real-Time Data Visualization, Low-Code Research Data Management.
Feel free to contact me for more details or visit us in the Laboratory.
Please note that we are currently unable to provide accommodation or financial support for your stay or visit. However, if this is not a limitation for you, mention it explicitly when contacting us.

Our Electronics are home brewed, step by step improved from the breadborad to PCB using KiCAD 3D model design.
Below are a set of 3D views showcasing an electronics board in action, navigating atom locations. We utilized the MCP4922 12-bit digital-to-analog converter and the MCP3208 8-channel analog-to-digital converter, along with a bunch of instrumentation ICs, to set up our lateral scanner electronics.
Breadboard DAC designed for our scanner, all under the control of a Raspberry Pi.
Upgraded PCB for the DAC, and universal board designed for a pre-amp (10^8 V/A) and PID circuit, powered by 2x 12 V batteries.
ADC with custom attenuation and bipolar to unipolar conversion unit
PID and pre-amp (of course not ideal, but does basic work)
More than 15 Python modules are in sync and counting up, for counting atoms!
We are currently employing a stepper motor with a worm gear setup for coarse and fine approach adjustments.
Our scanning mechanism currently utilizes a piezoelectric
budget-friendly piezoelectric plate that works fair enough to see atoms, as tested by many DIY hobbyist
The instrument consists of both monochromatized and non-monochromatized X-ray light, and ultraviolet light sources. It also includes a hemispherical electron energy analyzer for photoemission spectroscopy studies.
For surface preparation, we have Ar gas sputtering, annealing (heating), and scraping facilities.
We are currently in the process of developing our own thermal evaporator suitable for:
