Today, more than fifty of his former students and postdocs hold prominent faculty positions at Universities around the world.

Magalí Alejandra Lingenfelder

Magalí Lingenfelder is currently leading the Max Planck-EPFL Laboratory for Molecular Nanoscience. Her vision is to create atomically tailored interfaces for applications in two distinct areas of urgent technological and societal relevance: energy conversion and smart antimicrobial interfaces. To access the nanoscale, her group uses a combination of state-of-the-art scanning probe microscopy and solid state spectroscopy, allowing the study of kinetic processes in-situ under liquid flow and potential control conditions (operando electrocatalysis). She made seminal contributions to the field of metal-organic coordination networks on solid surfaces, and received the Otto Hahn medal in 2008 for the microscopic understanding of the chiral recognition process with submolecular resolution. She is a committed mentor, and since her relocation from the Lawrence Berkeley National Laboratory, USA to EPFL in 2013, she directed 3 MSc. theses, 4 PhD theses and 4 postdocs. She advocates for problem-oriented interdisciplinary research: she led 5 international research consortiums, delivered over 40 invited presentations and organized 9 conferences and 4 doctoral schools. In 2018, the Royal Society of Chemistry included her work in the first collection “Celebrating Excellence in Research: 100 Women of Chemistry”.

Scanning tunneling microscope

A scanning tunneling microscope (STM) is a type of microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer, then at IBM Zürich, the Nobel Prize in Physics in 1986. STM senses the surface by using an extremely sharp conducting tip that can distinguish features smaller than 0.1 nm with a 0.01 nm (10 pm) depth resolution. This means that individual atoms can routinely be imaged and manipulated.

Quantum tunnelling

In physics, quantum tunnelling, barrier penetration, or simply tunnelling is a quantum mechanical phenomenon in which an object such as an electron or atom passes through a potential energy barrier that, according to classical mechanics, the object does not have sufficient energy to enter or surmount. Tunneling is a consequence of the wave nature of matter, where the quantum wave function describes the state of a particle or other physical system, and wave equations such as the Schrödinger equation describe their behavior.

Simple random sample

In statistics, a simple random sample (or SRS) is a subset of individuals (a sample) chosen from a larger set (a population) in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way. In SRS, each subset of k individuals has the same probability of being chosen for the sample as any other subset of k individuals. A simple random sample is an unbiased sampling technique. Simple random sampling is a basic type of sampling and can be a component of other more complex sampling methods.

Sampling (statistics)

In statistics, quality assurance, and survey methodology, sampling is the selection of a subset or a statistical sample (termed sample for short) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population. Sampling has lower costs and faster data collection compared to recording data from the entire population, and thus, it can provide insights in cases where it is infeasible to measure an entire population.

Stratified sampling

In statistics, stratified sampling is a method of sampling from a population which can be partitioned into subpopulations. In statistical surveys, when subpopulations within an overall population vary, it could be advantageous to sample each subpopulation (stratum) independently. Stratification is the process of dividing members of the population into homogeneous subgroups before sampling. The strata should define a partition of the population.
