My name is Ishita, and I am a PhD student at the Technical University of Darmstadt. Alongside my doctoral research, I am independently developing BioCabinet as a personal project, separate from my PhD work.
I started this project with the goal of making genomic data analysis more accessible to wet-lab scientists, particularly those who face steep technical barriers when working with complex, multi-modal datasets. BioCabinet is designed to bring multiple analytical tools together in one place, offering users the flexibility to compare methods, explore results across modalities, and access integrated documentation directly within the analysis workflow.
A key motivation behind this project is to continuously evolve the platform alongside emerging technologies. This includes incorporating LLM-based chatbots trained on extensive biological and technical documentation, enabling researchers to ask questions, navigate tools, and better understand their data in an intuitive way.
Through this project, I aim to contribute a community-driven, up-to-date analysis framework that lowers the barrier to entry for advanced genomics research while remaining adaptable to future developments in the field.

Education
- German Diplom-Ingenieur Wasserwirtschaft (5 years) at University of
Technology Dresden,
Germany -- Wasserwirtschaft literal translation water management, engineering
degree in water resources management with focus on groundwater hydrology and
modelling - MS in Hydrology and Water Resources at University of Arizona, Tucson, USA
- Ph.D. in Mining Hydrology at BTU Cottbus, Germany -- Development of a coupled
surface water and groundwater model for open pit mine lakes (PITLAKQ)
Work Experience
- Combination of hydrology and software development
- Coupling of models
- Python teaching -- since 2004, >1500 full teaching days with focus on scientist and engineers
Model Coupling
I have experience in coupling different hydrological and hydraulic models, such as:
PITLAKQ
This is my Ph.D. work that couples a finite volume groundwater model (PCGEOFIM),
a hydrodynamic and water quality lake Model (CE-QUAL-W2), and a
hydro-geo-chemical model (PHREEQC).
PITLAKQ is open source.
It has been applied world wide.
I used it for pit lakes in Germany, Australia, and Canada.
Others have used it in many other countries of the world.
Coupling of a river flood model and a groundwater model
I have been involved in a research project that couples a river model, a sewer
pipeline model and groundwater model for the river Elbe in the city of Dresden,
Germany.
I was responsible for the coupling of the river model and the groundwater
model.
Rainfall runoff model -- groundwater model
I implemented a coupling of a rainfall runoff model (ArcEGMO) and a groundwater
model (PCGEOFIM) for a watershed in Germany.
Density-driven flow in groundwater and lake
I coupled a density-driven groundwater flow and transport model (MODMST) to
PITLAKQ.
This was used for a long-term simulation of a sub-aquatic landfill,
i.e. a lake over a deposit of mining waste.
MODFLOW with dynamic boundary conditions - pymf6
I am the developer of pymf6
that allows to interact with MODFLOW 6 via Python at runtime.
This can be used to implement dynamic boundary conditions.
Examples are:
- water-level-controlled wells that dynamically adjust their pumping rates
based on simulated water levels in the aquifer - dynamic values of the resistance of the colmation layer at the river bottom
that depend on the flow direction between river and aquifer - technical heat boundary conditions in urban settings such as building
basements and tunnels
MODFLOW 6 with AEM
I coupled an Analytic Element Model (AEM)
TTim with MODFLOW 6
via pymf6.
This allows to combine the grid-based approach of MODFLOW with the analytic,
grid-less approach of AEMs.
MODFLOW 6 with PHREEQC -- rtmf6
I coupled MODFLOW 6 with the geochemical model PHREEQC via
PhreeqPyusing
PhreeqcRM.
I am the author of PhreeqPy.
The result is rtmf6.
