- Nov. 2019 -- today: (tenure-track) Lecturer (Eng.: Assistance Professor) at ANU. I gave and probably will give several Guest Lectures on AI, Planning, and Games. Teaching-wise, my main responsibility is, however, teaching the Logic course, which I will co-deliver with (Lecturer) Yoshihiro (Yoshi) Maruyama.
- Oct. 2016 -- Oct. 2019: Project coordinator (over the entire runtime) of the technology transfer project Do it yourself, but not alone: Companion-Technology for Home Improvement, which was a collaboration between two Institutes of Ulm University and the Corporate Research Sector of Robert Bosch GmbH.
- July 2009 -- Dec. 2017: Dr. rer. nat. at the Institute of Artificial Intelligence of Ulm University, Germany. My supervisor was Prof. Dr. Susanne Biundo-Stephan.
- Oct. 2003 -- June 2009: Studies of Computer Science (Diploma, which is roughly Bachelor + Master in one degree) at the University of Freiburg, Germany.
I am doing research in the fields of Hierarchical Task Network (HTN) Planning and Partial Order Causal Link (POCL) Planning. I'm interested in theoretical foundations (mostly complexity analyses), algorithms, and heuristics of/for those fields. For a more detailed description of my research interests see the respective tab or check out some of my papers.
- May 2021: I have a fully funded PhD scholarship available. Please apply!
- May 2021: Submission deadline for the ICAPS workshop on Hierarchical planning is at May 12th. Please apply!
PhD under my Supervision:
- Scholarships / Funding: I have a fully funded scholarship available! Please apply!
- Who can apply? Pretty much everyone, but I assume that you are are worth my time, so please don't let me down. Obviously, having attended courses like Artificial Intelligence (search, heuristics, planning etc.) would be invaluable, but also general computer science courses like Complexity Theory / Theory of Computation, or even Graph Theory could suffice. Just convince me that you have what it takes to be successful! I have high expectations from anybody I supervise, but in exchange I offer an for-me-unhealthy amount of supervision and guidance as payback. Also, my field is super-interesting, and there is a lot to explore, so take the opportunity!
- How to apply? First of all, write your email with care, I do not want to see obvious mistakes and carelessness. Don't worry if you are not perfect in writing (or speaking) English, I do not care about this! But I care about the effort you put in. I will let you decide what to put into your application, but clearly I require a transcript and a few sentences about your background and why you would like to pursue a PhD under my supervision at ANU in the field of planning. I might then give you a very few papers to read so we can have an interview about it. Pass that and we see further.
- Further information? Read the ANU PhD scholarship info page and some more information on ANU MPhil and PhD scholarships and applications.
- PhD in Planning at another University? If you are a great student, then of course I would love to supervise you! Sadly, there is always limited funding, so I cannot accept everybody. PhD positions in planning from everywhere around the world are regularly posted over the following two mailing lists, so you might consider subscribing them - only if your application with me is isn't successful! ;)
- planning-list~AT~googlegroups.com. The is a general mailing list for planning.
- icaps-conference~AT~googlegroups.com. This belongs to the ICAPS conference series, the premier conference on Automated Planning and Scheduling.
Before I joined ANU I was also involved in teaching at two other Universities: University of Freiburg, Germany (where I was still a student) and at Ulm University, Germany, where I did my PhD and (almost) two years of post-doc.

- Intelligent Planning (SS 18)
- Intelligent Planning (WS 17/18)
- Intelligent Planning (SS 17)

Seminars organized and supported:
I was a supervisor for one to three seminar participants in all of the following seminars:
- Artificial Intelligence (SS 19) -- this seminar was organized by me
- Artificial Intelligence (SS 18)
- Artificial Intelligence (WS 17/18)
- Artificial Intelligence (SS 17)
- Artificial Intelligence (SS 16)
- Artificial Intelligence (WS 15/16)

I did also do supervision:
- 3 Diploma or Master Theses (Diploma Theses do not exist anymore, they are essentially the same as Master Theses). Master Theses are essentially the same as 24 point Honours research projects at ANU.
- 9 Bachelor Theses. A Bachelor theses can be regarded a bit more than a 12 point research project at ANU.
- 5 Projects and Practicals. These can differ severely in their length and can be compared with either 12 or even 24 point research projects at ANU. The major differences are that they are focused on programming something, so there does not need to be any scientific research involved. Secondly, students are only required to write a "report" rather than a "thesis", which is not nearly as scientific and long as a thesis required to be.
University of Freiburg
While I was still a student of Computer Science at the University of Freiburg, I was a tutor for several lectures. There, being a tutor implied correcting exercises (and exams, but don't tell! :)) and being a lecturer of the respective practice groups. These are the respective lectures:
- Formal Methods and Programming (WS 08/09, Lecture of Cognitive Science)
- Foundations of Artificial Intelligence (SS 08)
- Foundations of Artificial Intelligence (SS 07)
- Computer Science I (WS 05/06)
As my doctoral thesis, my research interests span from theory to practice -- content-wise all is concerned with either Hierarchical Task Network (HTN) planning or Partial Order Causal Link (POCL) planning.
Hierarchical Task Network Planning
Short explanation of HTN planning: HTN planning is an approach to planning that's centered around problem decomposition. We are given an initial task network -- a partially ordered set of primitive or compound (or abstract) tasks. Primitive tasks are the actions known from classical planning, i.e. they specify preconditions and effects stating in which states they are applicable and how they chance a state if applied. Compound tasks are just abstracts of pre-defined task networks, so they are essentially just (parametrized) names like go(Canberra,Sydney). The planning model specifies rules how they can be achieved. These rules, called decomposition methods, are simply mappings to pre-defined task networks, which can in turn contain compound tasks. The goal is to refine the initial task network into a primitive one that is executable. HTN planning is more expressive than classical planning, where this mechanism of task decomposition does not exist. In its most general form (as just explained) it's undecidable.
My research interests in HTN planning are, roughly ordered by my interest:
- Design of well-informed heuristics. (This is still a young field with only a limited number of heuristics available.)
- Investigation of the computational complexity of various problems like the plan existence problem (how hard is it do decide whether there exists a solution?)
- Essentially all questions that are related to incorporating human users into the loop. These comprise:
- Plan abstraction and presentation (how can plans be presented on a more abstract level? can we stop planning on more abstract levels?)
- Plan linearization and presentation (in which order should plan steps be presented to a human user so that the pan's execution order seems reasonable?)
- Plan explanations (how to find reasonable explanations for plans and how they look like?)
Partial Order Causal Link (POCL) Planning
Short explanation of POCL planning: POCL planning is a technique for solving classical panning problems, where we would like to find a plan in order to achieve some (state-based) goals. In POCL planning, this is done in the space of partially ordered (also called non-linear) plans. Search is done in a regression-like fashion starting with the goals: select a condition not yet achieved (called "open") and select an appropriate action (i.e., with matching effect) from the plan or model and "document" that goal achievement by the insertion of a so-called causal link. Tis procedure is repeated until a goal plan has been found. Since search nodes are partially ordered plans (rather than states as in standard progression search), heuristic desingn is much more complicated.
Some more background of POCL planning: Since roughly 15 years this kind of problem solving is generally regarded outdated (some even say obsolete!) because state-based progression search is simply much more efficient nowadays. However, this argument is a purely empirical one. Moreover, there is a vast variety of well-informed heuristics in classical state-based planning, but almost none exist in POCL planning. Hence, it's interesting to imagine where POCL could be by now if we had as well-informed heuristics for that search as well. (Whether this can even be is another question, as some of my theoretical results indicate that heuristic design is computationally harder than in the progression setting.) Another important note to make is that POCL techniques are still used in hierarchical planning, as one of the few standard techniques for solving HTN problems relies on POCL planning techniques.
My research interests in POCL planning are, roughly ordered my interest:
- Design of well-informed heuristics. (Again, almost no heuristics exist so far!)
- Investigation of the computational complexity related to POCL plans (such as the plan existence or plan optimization.)
Well, most that I am interested in is already covered above as part of HTN planning: When ever one integrates a human into the loop, several new questions arise that need to be addressed in a systematic way. For instance, once we have found a solution to a problem (i.e., a plan) that plan can be executed successfully as otherwise it wouldn't be a solution. However, for a human it might be a big difference in which order its actions are executed (by him or her) since there might be a switch of contexts that could be confusing or even annoying. Finding a reasonable (we called it "user-friendly") reordering is one such task that can be investigated on both a formal and an empirical level. Other related questions, as mentioned above, are the presentation of plans on higher levels of abstraction and the explanation of plans.
Another important aspect in the practical application of planning technology is the planning language's level of expressiveness. In order to solve real-world problems, we need to be able to express time (at the least!) or more generally functions. This will require new formalisms, reductions, and heuristics.

- ICAPS 2019 Best Dissertation Award
For my dissertation Hybrid Planning -- From Theory to Practice
Award description from ICAPS website:
The dissertation stands out by covering a lot of ground:
It formalizes and develops planning with hierarchical task networks (HTNs) toward a hybrid formalism that includes partial-order causal link planning;
it presents complexity results for the resulting problem classes;
it develops heuristics for hybrid planning;
it describes the implementation of a hybrid planner and its integration into a companion device that assists in the set-up of a home theater system; and
it performs a user study to evaluate the system. The dissertation also rekindled interest in HTN planning by putting it on firm formal ground and connecting it to recent developments in classical planning.

Entertainment - (Not work-related!)
Although this is not a "private" webpage, I still decided to add some stuff that has pretty much nothing to do at all with work. Well, not directly, that is. It turns out that many computer scientists share a very similar humor. And here I share it with everybody! The second part is not on humar but education covering topics like medicine/biology (like vaccinations), physics/space travel/the universe, and even math.
Well, there are countless "Best of" lists you can easily google for by yourself, so I don't see the point providing yet another list here. I just try to obtain a bit of "culture" by making aware of it! Simply it's so old already that current students stop even knowing it. So, I just give two of the most famous sketches (google for more!).
Fun fact: Did you know that the name of the programming language python is a tribute to Monty Python? There are further references, such as using "spam and eggs" in comments (etc.) instead of the typical "foo and bar". (see wikipedia)
- Argument Clinic [just the part about having an argument] (e.g., https://www.dailymotion.com/video/x2hwqn9)
- Spam (e.g., https://www.dailymotion.com/video/x2hwqlw)
Did you know that the expression "SPAM" for the endless flooding with unwanted content comes from exactly this sketch? If you are a computer scientist: you should know! (see wikipedia)
If you are a computer scientist (or a mathematician etc.), you very likely know these great comics, anyway! Still, here is a selection that's highly related to us (computer) scientists:
- The difference [between scientists and non-scientists] (https://xkcd.com/242/) -- fun fact: as a young undergraduate that was the first xkcd comic I've ever seen, and I was sure to be the person on the right
- Nerd Sniping (https://xkcd.com/356/)
- Correlation (https://xkcd.com/552/)
- Is it worth the time? (https://xkcd.com/1205/)
xkcd also features what if? (https://what-if.xkcd.com/) -- serious scientific answers to absurd hypothetical questions. (You might know this from the big bang theory... :))
Well, xkcd is (imho) worlds better, because it is really smart (and nerdy) humor. PhD comics are not "smart", but they tell the story of PhD students (or researchers, no much difference there, actually), so they are also great! Just for a different reason.
- List of the 200 most popular comics (http://phdcomics.com/comics/most_popular.php)
Education Channels on YouTube
- Kurzgesagt: An amazing YouTube channel covering all different kinds of scientific topics, most are related to physics and the Universe, but they cover many other topics like medicine as well. The name is German for "in a nutshell", but the content is English! (Though they've recently launched a German channel as well.)
- VSauce: Another absolutely amazing YouTube channel! :) It covers so extremely many topics that it's hard to even describe it in the first place. They even cover technical topics like number theory, but also every-day topics like the placebo effect. What stands out is how entertaining it is despite explaining everything on a scientific level while still being easy to grasp.
- Ted Talks: Some "private people" give an interesting talk about what they personally care about (in an interesting and entertaining way). Many are scientists or Professors, others are entrepreneurs. A very few people just seem to be self-promoters who like hearing them talk^^, bit the vast majority is actually quite amazing. Literally every topic is covered.
- Last week Tonight: A comedy/entertainment show, but all the content covered is of an educational nature. Much of it is tailored to the USA, but many topics generalize. Although using
- Adam ruins everything: Like Last week tonight, this is clearly entertainment and comedy, but again the content is educution. The show explains common myths, i.e., wrong every-day "knowledge". It also shows where certain traditions come from - most of the time "ruining" them. :)
- There are some other "educating" channels that I like, though they are not that serious than the others, so I'm not mentioning them here publicly. :) You can ask me if interested!
